I paid 40,000.00 of my student loan in 2019 where do I put it on my taxes?

You do not deduct all the loan repayments. You can only deduct your student loan interest up to a maximum of $2,500. To claim the deduction, enter your form 1098-E.

To enter your form 1098-E 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 Student Loan Interest Paid (Form 1098-E)
