You can add it in the Education section of TurboTax. It will be in the section that also asks about a 1098-T, but just state you did not receive one. Eventually you will be brought to a screen that asks whether you received a scholarship or a grant. There you can specify "YES" and then you will be given an option to enter the amount. Further questions will ask if the scholarship/grant covered room and board or just tuition. See more information below:
