How do I enter quarterly tax payments that I made in 2024? The instructions say to go to "Estimates and Other Taxes Paid", but that doesn't exist.

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

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

*** Update ***

I was able to force TT to show the missing section:

1) Under the "Deductions and Credits" section, click on "Add Tax Breaks"

2) Search for "Estimate"

3) Click "Add" next to "Estimated Tax Payments".

This makes the missing section become available.
