Where do I input the Federal Taxes I paid in 2023 in Turbotax?

To enter, edit or delete estimated taxes paid (Federal, State, Local) -

Click on Federal Taxes (Personal using Home and Business)
Click on Deductions and Credits
Click on I'll choose what I work on (if shown)
Scroll down to Estimates and Other Taxes Paid
On Estimates, click on the start or update button

Or enter estimates paid in the Search box located in the upper right of the online program screen. Click on Jump to estimates paid

You do not enter the federal tax you paid for tax due last year.   It is not deductible.

 

 

 

Or are you asking about estimated quarterly payments that you made?

 

 Go to Federal>Deductions and Credits>Estimates and Other Taxes Paid>Other Income Taxes
