If I paid for my tuition out of pocket, how do I claim it as an expense?

To check for education credits, you have to enter your 1098-T in your tax return. Please note that if you are a dependent of your parents, you cannot claim education credits. Only they can.

To enter your form 1098-T in TurboTax, follow these steps:

1. Open your tax return
2. Click on Federal in the left panel.
3. Click on Deductions & Credits at the top
4. Scroll down to the Education section. Click Show more 
5. Select Start next to Expenses and Scholarships (Form 1098-T)
6. On the next page, click on Add a Student. Or if the student has already been added, click on Edit next to the name of the student. After a few screens, answer Yes on the page Did [student] get a 1098-T for the year 2019?
