How can I find out the amount of tuition that was paid:?

Have you checked with your school or university? They should have supplied you with a 1098-T. If not, they can usually be accessed from your school's website. Or if you kept records of how much you paid, you can use that.

Now let's enter that 1098-T form:

1. Open (continue) your return, if you're not already in it.
2. In TurboTax, search for 1098T (lower-case works also) and then click or tap the "Jump to" link in the search results.
3. Answer any education questions that pop up (enrollment status, name of school, and so forth).
   • If you land on the Education Expenses Summary screen, click or tap Edit next to the student in question, then edit the Tuition item.
4. At the Did you get a 1098-T? screen, answer Yes and continue.

After you enter your 1098-T, we'll ask about other expenses (books, supplies, equipment) and financial aid.
