You cannot claim a tuition credit unless:
1. Your son is your dependent
2. His school issues a 1098-T or you have a valid exception for not having one
The TurboTax (TT) interview handles all of this.
In TurboTax (TT), enter at:
Federal Taxes Tab (Personal for H&B version)
Deductions & Credits
-Scroll down to:
--Education
--Education Expenses
Follow the interview to completion. In particular, at the 1098-T screen, note the link "What if this is not what I paid the school" underneath box 1. There you will be able to enter the actual amounts of tuition and fees paid. Later, you can enter books and other course materials.
