It's not clear what you're saying. Was the rent included in the box 5 amount on the 1098-T? If yes, then it is additional income and TurboTax (TT) will treat it like ordinary scholarship (apply to the box 1 tuition first, then treat any excess as taxable). If you want to designate it as taxable (for example to free up tuition for you, or your parents to claim the tuition credit), answer yes when TT asks if any of the grant was used for room & board.
