I wasn't required to buy a book in the syllabus, but I have to buy several to finish a major paper because it was the only way to get them. Do I include this; Where?

Yes, there are additional screens besides the 1098-T to enter the expenses. 

1. Type   education expenses   into the search box
2. Click on "Jump to education expenses"
3. Click Edit next to your name
4. Click Edit next to "Other Education Expenses (for all schools)"
