Lots of posts on this. If you're using a desktop version and can get to Forms (top right toolbar), go to Forms, pick the Student Info form, and go to Part IV. It will say you can't enter anything there, but there's a QuickZoom button to take you to the student's People Worksheet (saves you from scrolling past all the other forms and worksheets to the very bottom of the federal inputs) and there you can go to Part VIII and enter all the books you paid the school for, books and materials you bought from elsewhere that were required, and computer, Room and Board, etc. Of course room and board isn't eligible for the AOTC, but you may get the full AOTC if you can claim part of a scholarship was used for room and board. See IRS Publication 970.
