I paid Estimated Tax in 2023, but I did not find any place in Turbo Tax allowing me to enter that. How to report the estimated tax I paid then?

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

Or click on Tax Tools on the left side of the online program screen.
Click on Tools
Click on Topic Search
Type in estimated tax payments, click on GO

Federal estimated taxes paid are entered on Form 1040 Line 26

Very simple. Go To Forms and Select Tax & Int. Wks. It lists both Federal and State Estimated Taxes (with dates).
