We affirm the trial court’s order denying appellant’s motion for 3.850 relief, without prejudice to appellant seeking administrative relief on his claim for gain time through the Florida Department of Corrections. See State v. Thompson, 750 So.2d 643 (Fla. 1999). See also Killings v. State, 567 So.2d 60 (Fla. 4th DCA 1990).
