Where do I add the estimated tax payments I made in 2024 to turbotax?

You'll enter them in the deductions section, under estimates and other taxes paid.

If you are using TurboTax Online 

• From the Tax Home screen locate and select Deductions and Credits. Scroll down to +Add Tax Brakes. 
• A menu will appear, locate the section for Estimates and other Taxes Paid. Click on add next to Estimated Tax Payments (this will add the section back to the main screen)
• Go back to the Tax Home screen and back to Deductions and credits. You will see the section added for Estimated Tax Payments. (click start)

If you are using TurboTax Desktop

• From the Main Screen select the Federal Taxes tab, then Deductions & Credits. 
• Scroll down until you see Estimates and Other Taxes Paid. Click start on “Estimates”
