At the 1098-T screen, in TT, there is a place to check box 7 (you have to scroll down).
To get back to that screen, go through the entire education interview until you reach a screen titled "Your Education Expenses Summary". Click edit next to the student's name. That should take you to a screen “Here’s your Education Summary”. Click edit next to the section you want to change; tuition, in your case (click edit next to the school name).
