Hi there- Looking for the location that I can input my Tuition Tax Credit via a private school donation. I cannot find it anywhere. I did it last year with no issues.

How to enter your 2020 charitable donations in TurboTax.

1. Open your return in TurboTax.
2. In the search box, search for donations and then select the Jump to link in the search results.
3. Answer No when asked if you have an ItsDeductible account (even if the answer is yes).
4. Answer Yes to Do you want to enter your donations for 2020?

Taxpayers are allowed to claim a deduction for donations they make to qualified organizations.  A qualified organization includes most nonprofit schools that operate exclusively for educational and literary purposes.

 Any school from preschool to graduate school qualifies, as long as it is ''not for profit''.   

What does "Tuition Tax Credit via a private school donation" mean?

There no such thing  on the federal return.  DawnC's reply describes how to claim an itemized deduction (not a tax credit) for  any charitable donation.

Are you asking about a state credit? Which state?
