   Before FLAUM, KIRSCH, and JACKSON-AKIWUMI, Circuit
Judges.
    JACKSON-AKIWUMI, Circuit Judge. John Fliss and Larry
Wojciak were once business partners. But their relationship
soured when their jointly owned companies defaulted on a
bank loan. After the bank obtained a consent judgment in
state court, Wojciak used one of his companies, Generation
Capital I, LLC, to take over as the judgment creditor and
2                                                 No. 22-1424

attempt to enforce the judgment against Fliss. When Fliss filed
for bankruptcy in federal court (because of his overall insol-
vency), Generation Capital I asserted a claim in the bank-
ruptcy proceedings against Fliss in the amount of the consent
judgment, plus interest. Fliss objected, and the bankruptcy
court disallowed Generation Capital I’s claim in its entirety.
   This appeal asks us to decide whether the bankruptcy
court violated the Rooker-Feldman doctrine by disallowing
Generation Capital I’s claim, or alternatively, whether the
prior state court litigation precluded Fliss from objecting to
Generation Capital I’s claim in bankruptcy court. We hold
that the bankruptcy court had subject matter jurisdiction to
consider the claim objection—the Rooker-Feldman doctrine
posed no obstacle—and that Fliss was not otherwise barred
from objecting to the claim. We therefore affirm.
                               I

   More than ten years ago, John Fliss, Larry Wojciak, and
Mark Barr went into business together. They took out a
$200,000 secured loan from a bank as working capital for their
two jointly owned companies. Each man personally guaran-
teed the loan, and a trust established in Sherry Wojciak’s
name (Larry’s spouse), was the fourth guarantor. When the
businesses failed and the borrowers defaulted on the loan, the
bank sought to recoup its losses in state court. In May 2011,
the state court issued a consent judgment in the amount of
$208,639.95 against Fliss, Barr, Wojciak, their companies, and
Sherry Wojciak’s trust, and held the four guarantors jointly
and severally liable.
   What happened next was either a stroke of ingenuity or
scheming, depending on who you ask: Wojciak negotiated a
No. 22-1424                                                              3

deal with the bank that allowed him to step into the bank’s
shoes as a judgment creditor. 1 He then sought to enforce the
entire amount of the debt against his former business part-
ners, Fliss and Barr. The feat was accomplished in multiple
steps, using three entities owned and operated by the
Wojciaks: Generation Capital, Generation Capital I, and Gen-
eration Capital II.
    Larry Wojciak’s initial moves were as follows: on February
24, 2012, he entered into a sale and assignment agreement
with the bank, through Generation Capital I, to purchase the
promissory note and judgment debt for $240,000. Two days
later, he also entered into a settlement agreement with the
bank under which he (and Sherry’s trust) agreed to pay
$240,000 to settle the judgment debt and have the loan docu-
ments assigned to Generation Capital pursuant to the sale and
assignment agreement. The next day, on February 27, Larry
Wojciak had Generation Capital II wire $240,000 to the bank.
See Generation Cap. I, LLC v. Fliss (In re Fliss), 

, 23–
24 (N.D. Ill. 2018). This transaction completed the first part of
Wojciak’s plan.
    Wojciak then kicked off the second part of his plan: step-
ping into the bank’s shoes in the state court proceedings. On
May 8, 2012, the state court entered an order substituting Gen-
eration Capital I for the bank as the plaintiff. Wojciak next
moved to enforce the judgment, through Generation Capital
I, against Fliss and Barr by commencing a supplemental pro-
ceeding and seeking turnover of property in satisfaction of the


    1 Although the transactions involved Sherry’s accounts and trust,

Sherry testified that her husband controlled all business and financial de-
cisions and that she signed documents because he asked her to.

judgment. Fliss and Barr filed a motion for determination in
the main proceeding, arguing that the debt was extinguished
when the Wojciaks paid $240,000 to the bank in exchange for
settling the judgment. The state court disagreed, found that
the settlement agreement was not executed, and entered a de-
termination order in May 2015 stating that the debt was still
owed.
    In August 2015, Fliss filed a voluntary Chapter 13 petition
in bankruptcy court. Chapter 13 allows an individual debtor
who cannot fulfill his financial obligations to submit to the
bankruptcy court “a plan for paying his creditors as much as
possible over a period of years, upon completion of which he
is given a discharge of his remaining dischargeable debts.” In
re Crawford, 

 (7th Cir. 2003). The Bankruptcy
Code requires creditors to file a proof of claim. FED. R. BANKR.
P. 3002(a). Thus, in December 2015, Wojciak had Generation
Capital I file a secured claim in bankruptcy court seeking to
enforce the entire state court judgment, now $359,967.69 in-
cluding post-judgment interest, against Fliss. Fliss objected to
the claim.
    The bankruptcy court disallowed Generation Capital I’s
claim in its entirety and approved the Chapter 13 plan pro-
posed by Fliss. The bankruptcy court found that Wojciak used
Generation Capital I as his alter ego and, as a result, became
both the creditor and debtor of the state court judgment. This
merger of interests extinguished the debt. As relevant on ap-
peal, the bankruptcy court further held that the doctrines of
Rooker-Feldman, res judicata, and collateral estoppel did not
bar it from deciding whether the claim should be allowed or
disallowed.
No. 22-1424                                                     5

    Generation Capital I appealed to the district court, which
affirmed the bankruptcy court’s ruling. We now consider
these issues.
                                II

    We review the bankruptcy court’s factual findings for
clear error and the legal conclusions of both the bankruptcy
court and the district court de novo. In re Kempff, 

 (7th Cir. 2017). Our review of the district court’s applica-
tion of the Rooker-Feldman doctrine is de novo. Andrade v. City
of Hammond, 

 (7th Cir. 2021).
    Generation Capital I advances two arguments on appeal.
First, it asserts that, under the Rooker-Feldman doctrine, the
bankruptcy court lacked subject matter jurisdiction to con-
sider the claim objection filed by Fliss. Alternatively, Genera-
tion Capital I argues that the doctrines of res judicata and col-
lateral estoppel bar the claim objection. We consider the
Rooker-Feldman issue first because it is jurisdictional.
    The Rooker-Feldman doctrine is a creature of two Supreme
Court decisions, Rooker v. Fidelity Trust Co., 

(1923), and District of Columbia Court of Appeals v. Feldman, 

 (1983). It “is a principle of jurisdiction that precludes
the lower federal courts from applying appellate review to
state court decisions.” Epps v. Creditnet, Inc., 

(7th Cir. 2003). “An action in federal court that alleges an in-
jury ‘inextricably intertwined’ with a state court decision,
such that success in the federal court would require overturn-
ing the state court decision, is barred by the Rooker–Feldman
doctrine.” 

6                                                             No. 22-1424

    The Rooker-Feldman doctrine is inapplicable here for at
least two reasons. First, Fliss did not file a federal suit seeking,
as a cause of action or prayer for relief, to set aside a state
court judgment. See 

 (federal court jurisdiction barred
by Rooker-Feldman where the plaintiffs’ “prayer for relief
ask[ed] the district court to set aside the [state court] judg-
ment . . . and ‘refund’ . . . the damages assessed by the state
court”). Instead, Fliss petitioned for bankruptcy court protec-
tion under Chapter 13 of the Bankruptcy Code because his in-
come and assets were not enough to meet his liabilities. The
issue of the state court judgment was only raised after Gener-
ation Capital I (not Fliss) filed a claim asserting a $359,967.69
secured debt and Fliss objected to that claim pursuant to fed-
eral bankruptcy law and procedures.
    Second, the state court never decided (nor could it) the
key issue facing the bankruptcy court in Fliss’s and Wojciak’s
dispute: whether Generation Capital I’s bankruptcy claim
should be allowed or disallowed under federal bankruptcy
law. “The Rooker–Feldman doctrine asks: is the federal plaintiff
seeking to set aside a state judgment, or does he present some
independent claim, 2 albeit one that denies a legal conclusion
that a state court has reached in a case to which he was a
party? . . . [I]f the latter, then there is jurisdiction.” GASH As-
socs. v. Village of Rosemont, 

 (7th Cir. 1993).
The state court judgment and the bankruptcy court’s disal-
lowance of Generation Capital I’s claim simply “are not two
sides of the same coin.” Remer v. Burlington Area Sch. Dist., 205

    2 We treat as the “independent claim” Fliss’s objection to Generation

Capital I’s claim. We recognize that the objection is not a claim in a tradi-
tional sense. Perhaps this incongruence is another indication for why
Rooker-Feldman is inapplicable here.
No. 22-1424 

 (7th Cir. 2000); see also Brokaw v. Weaver, 

 (7th Cir. 2002) (Rooker-Feldman not applicable where
state court proceeded under state law allowing only consid-
eration of state law question); Zurich Am. Ins. Co. v. Super. Ct
of Cal., 

 (7th Cir. 2003) (Rooker-Feldman did
not bar jurisdiction because federal claim arose under federal
law and existed irrespective of state court’s handling of state
law issues).
    Generation Capital I argues that we can glean Fliss’s intent
to attack the state court judgment because Fliss wrote in his
briefs before our court, the district court, and the bankruptcy
court that the state court “got it wrong.” But those statements
alone do not make Rooker-Feldman applicable. Zurich Am. Ins.
Co., 326 F.3d at 823–24 (“A mere assertion that a [lower fed-
eral] court, in considering a claim that is independent of the
state court judgment, might negate a legal conclusion that the
state court reached is insufficient to trigger application of
Rooker–Feldman.”); Long v. Shorebank Dev. Corp., 

,
555–56 (“[T]he fact that the plaintiff’s pursuit of his federal
claims could ultimately show that the state court judgment
was erroneous [does] not automatically render Rooker–Feld-
man applicable.”).
    We next turn to Generation Capital I’s argument that the
claim objection filed by Fliss is barred by the doctrines of res
judicata and collateral estoppel. While different in scope, both
doctrines function to preclude a party from relitigating issues
decided in a prior adjudication. The party asserting res judi-
cata and collateral estoppel as an affirmative defense must
show that a final judgment on the merits was entered in the
prior proceedings. Rein v. David A. Noyes & Co., 

 (Ill. 1996) (res judicata); Am. Fam. Mut. Ins. Co. v.
8                                                              No. 22-1424

Savickas, 

 (Ill. 2000) (collateral estoppel).3
Generation Capital I argues that the state court entered two
orders that satisfy the final judgment requirement: the con-
sent judgment entered in 2011 and the determination order
entered in 2015. Neither order has the effect Generation Cap-
ital I would like to assign it.
    Take the consent judgment first. We agree with the district
court that it was a final judgment, but it ultimately has limited
preclusive effect. The district court based its conclusion, at
least in part, on the bankruptcy court’s finding that a judg-
ment obtained by confession has a limited preclusive effect
because it is not “actually litigated.” Indeed, Illinois courts are
generally “reluctant to give preclusive effect to consent judg-
ments.” Ekkert v. City of Lake Forest, 

 (Ill.
App. Ct. 1992). We must, however, add a critical observation
to the analysis: consent judgments are treated differently un-
der res judicata and collateral estoppel doctrines, and neither
the district court nor the bankruptcy court acknowledged this
distinction.
    A consent judgment is not entitled to collateral estoppel
effect because the doctrine of collateral estoppel relies on “ac-
tual” litigation of issues in the prior proceeding, Savickas, 

, while a consent judgment is “an administrative
act of the court recording an agreement of the parties, rather
than a judicial determination of the rights of the parties and
the issues involved,” Arnett v. Env’t Sci. & Eng’g, Inc., 657


    3 We apply Illinois law to this question of preclusion because “the pre-

clusive effect of a state court judgment in a federal case is a matter of state
rather than of federal law.” CIGNA Healthcare of St. Louis, Inc. v. Kaiser, 

 (7th Cir. 2002).
No. 22-1424 

, 673 (Ill. App. Ct. 1995). See also Meyer v. Rigdon, 

 (7th Cir. 1994) (“[A] default judgment is nor-
mally not given preclusive effect under the collateral estoppel
doctrine because no issue has been ‘actually litigated.’”);
Klingman v. Levinson, 

 (7th Cir. 1987) (con-
sent judgments not given preclusive effect unless parties
clearly indicate that intent).
     The question of whether res judicata applies to the consent
judgment is more complicated. There is an unresolved split in
Illinois appellate courts as to whether dismissal pursuant to a
settlement agreement amounts to a final judgment on the
merits for res judicata purposes. Jackson v. Callan Publ’g, Inc.,

, 427–28 (Ill. App. Ct. 2005); see also Urban v. J.P.
Morgan Chase & Co., 

. Under
a “modern view,” Illinois courts “generally recognize[] that a
valid consent judgment is entitled to a res judicata effect, so
as to preclude relitigation of the same claim or cause of action
as was covered by such judgment.” Jackson, 

.
The district court affirmed the bankruptcy court’s conclusion
that the consent judgment is a final judgment, and Fliss does
not contest that finding on appeal. We therefore proceed with
the assumption that the consent judgment has preclusive ef-
fect pursuant to the res judicata doctrine and focus our anal-
ysis on the extent of the preclusion here.
    The consent judgment is brief—it simply states the
amount owed to the bank by each of the four guarantors and
the companies jointly owned by Fliss, Barr, and Wojciak. The
district court affirmed the bankruptcy court’s finding that the
consent judgment “has limited preclusive effect—only as to
the existence of the debt and its amount.” We agree because a
consent judgment “is conclusive with respect to the matters
10                                                   No. 22-1424

settled by the order, judgment, or decree.” Elliott v. LRSL En-
ters., Inc., 

 (Ill. App. Ct. 1992) (emphasis
added); see also Arizona v. California, 

 (2000)
(noting that under federal law, “consent agreements ordinar-
ily are intended to preclude any further litigation on the claim
presented but are not intended to preclude further litigation
on any of the issues presented” (emphasis added)). The mat-
ters settled by the consent judgment were only the existence
of the debt and its amount: “Judgment by confession in the
amount of $204,797.70 plus $407 costs and $3,435.25 attor-
ney’s fees is entered against John W. Fliss.” We therefore see
no reason to disagree with the district court on the limited
preclusive effect the consent judgment has in the present liti-
gation.
    The state court’s determination order is the last obstacle
Generation Capital I raises to thwart Fliss’s claim objection—
unsuccessfully so, though for different reasons. To explain,
we begin with an overview of a relevant procedural mecha-
nism used by judgment creditors in Illinois—initiation of sup-
plemental proceedings to recover on the judgment, also
known as Section 2–1402 proceedings. 735 Ill. Comp. Stat. 5/2–
1402(a); see Stonecrafters, Inc. v. Wholesale Life Ins. Brokerage,
Inc., 

 (Ill. App. Ct. 2009). At the conclusion of
these supplemental proceedings, the presiding court may or-
der a turnover of the judgment debtor’s assets to the judg-
ment creditor. GE Betz, Inc. v. Zee Co., 

 (7th
Cir. 2013). An order entered in supplemental proceedings is
final when the judgment creditor “is in a position to collect
against the judgment debtor or a third party,” or has been “ul-
timately foreclosed from doing so.” Inland Com. Prop. Mgmt.,
Inc. v. HOB I Holding Corp., 

 (Ill. App. Ct.
2015).
No. 22-1424                                                   11

    Turning back to the facts of this case, consider how Gen-
eration Capital I obtained the determination order. After tak-
ing over as the judgment creditor, it brought a supplemental
proceeding in state court and filed a motion that sought,
among other things, an order directing Fliss to turn over his
real property in satisfaction of the consent judgment. The
judge presiding over the supplemental proceeding declined
to rule on the turnover motion until “the issue concerning a
determination as to the amount which may be due and ow-
ing” to Generation Capital I was decided. This prompted Fliss
(and Barr) to file a motion in the primary proceeding arguing
that the debt had been extinguished when the Wojciaks set-
tled the judgment with the bank. The judge presiding over the
main proceeding disagreed and in May 2015 entered a deter-
mination order stating that the debt was still owed and due to
Generation Capital I.
    Does this make the determination order a final order? We
think not. Illinois Supreme Court Rule 304 governs appeals
from final judgments that do not dispose of the entire pro-
ceeding. Rule 304(a) requires “an express written finding” by
the court “that there is no just reason for delaying either en-
forcement or appeal or both.” ILL. SUP. CT. R. 304(a); see Xcel
Supply LLC v. Horowitz, 

 (Ill. App. Ct. 2018).
The determination order did not include this special finding,
meaning that it is not a final appealable order under Illinois
rules. Generation Capital I insists that the court was not re-
quired to include a special finding because the determination
order was “[a] final judgment or order entered in a proceed-
ing under section 2-1402,” which is excepted under Rule
304(a). ILL. SUP. CT. R. 304(b)(4); Xcel Supply LLC, 

. We are not persuaded by Generation Capital I’s argu-
ment for three reasons.
12                                                    No. 22-1424

    First, to state the obvious: the exception does not apply
here because the determination order was entered in the main
proceeding, not the supplemental proceeding. In re Marriage
of Arjmand, 

 (Ill. App. Ct. 2017) (“[T]he
plain language of Rule 304(b)(4) is unambiguous: it permits
interlocutory appeals only from final judgments entered in ci-
tation proceedings under section 2-1402 of the Code.”).
    Second, but no less evident: there was no final judgment
in the supplemental proceeding when the determination or-
der was entered. To the contrary, the supplemental proceed-
ing had pending turnover motions filed by Generation Capi-
tal I that could be decided only after the determination order
was entered.
    Finally, because Generation Capital I’s turnover motions
had not been decided, it was not “in a position to collect
against the judgment debtor or a third party.” Inland Com.
Prop. Mgmt., Inc., 

; see also Chi. Police Sergeants’
Ass’n, Policemen’s Benevolent & Protective Ass’n, Unit 156A v.
Pallohusky, 

, 1128 (Ill. App. Ct. 2017) (a turnover
order was final under Rule 304(b)(4) where it “require[d] the
payment of specific assets to a judgment creditor” and put the
creditor in a position to collect). True, the determination order
stated that “[t]here remains an outstanding judgment
against” Fliss and others “in the amount of $204.797.70.” But,
unlike a turnover order, it did not “requir[e] the payment or
liquidation of assets to satisfy a judgment.” Pallohusky, 86
N.E.3d at 1127–28 (collecting cases).
   Thus, neither the consent judgment nor the determination
order was a final judgment that, under the doctrines of res ju-
dicata and collateral estoppel, precluded Fliss from objecting
No. 22-1424                                                     13

to Generation Capital I’s claim in bankruptcy court and rais-
ing the arguments he did in the process.
    In closing, we note a key gap in the record and Generation
Capital I’s preclusion arguments: the state court entered a
turnover order in the supplemental proceedings in July 2015.
This order put Generation Capital I in a position to collect the
judgment against Fliss’s real property. Had the order been in-
cluded in the record and relied on for arguments, it would
indeed qualify as a final judgment under Illinois Supreme
Court rules. But Generation Capital I never presented this or-
der—before our court, the district court, or the bankruptcy
court. Arguments not raised in the district court are waived
on appeal, Brown v. Auto. Components Holdings, LLC, 

 (7th Cir. 2010), and “raising an issue in general terms
is not sufficient to preserve specific arguments that were not
previously presented,” Puffer v. Allstate Ins. Co., 

 (7th Cir. 2012). Moreover, it was Generation Capital I’s
burden to demonstrate that the affirmative defenses of res ju-
dicata and collateral estoppel apply, Oshana v. FCL Builders,
Inc., 

 (Ill. App. Ct. 2013) (res judicata); Peder-
son v. Village of Hoffman Ests., 

, 1095 (Ill. App. Ct.
2014) (collateral estoppel), just as it was Generation Capital I’s
responsibility “to allege facts and indicate their relevance un-
der the correct legal standard,” Econ. Folding Box Corp. v. An-
chor Frozen Foods Corp., 

 (7th Cir. 2008) (inter-
nal quotations omitted).
   Generation Capital I had numerous opportunities to pre-
sent the state turnover order and argue its finality in this case.
But at every stage of litigation, it steadfastly relied on other
orders to convince us, the district court, and the bankruptcy
court that it had obtained a final judgment in state court. Even
14                                                 No. 22-1424

when asked at oral argument about the turnover order, coun-
sel for Generation Capital I once again referred us to the de-
termination order. Under these circumstances, we have no
doubt that Generation Capital I waived any arguments con-
cerning the finality of the turnover order for purposes of res
judicata and collateral estoppel. We therefore do not consider
the turnover order in deciding this appeal. See, e.g., Lauth v.
Covance, Inc., 

 (7th Cir. 2017) (“[W]e can in-
voke waiver sua sponte . . . .”).
    Having found that Generation Capital I failed to demon-
strate the existence of a final judgment as required by both res
judicata and collateral estoppel, we do not address the parties’
arguments about the other elements of these doctrines. Simi-
larly, we do not reach Generation Capital I’s argument about
the bankruptcy court’s disallowance of its claim as a discov-
ery sanction.
                              III
    Rooker-Feldman is an important principle that preserves
appellate review of state court decisions exclusively for the
Supreme Court. It does not bar federal bankruptcy courts
from deciding issues of federal bankruptcy law. To hold oth-
erwise would expand the doctrine far beyond its reach. Ac-
cordingly, Rooker- Feldman was not an obstacle when Fliss ob-
jected to Generation Capital I’s claim, and neither were the
doctrines of res judicata and collateral estoppel.
                                                  AFFIRMED.
