From the books and supplies screen, continue through the subsequent screens until you get to "Your Education Expenses Summary." On that screen, click the Edit button for the student in question. On the next screen, click the Edit button for the college that the 1098-T is from. Two screens after that you will get to the 1098-T entry screen and you can enter the tuition. After you enter it, be sure to continue through the rest of the interview to the screen to maximize your education credit.
