You have to enter the extension payment that you made in TurboTax. In the Search box type "estimated tax payments" (without the quotes), then click the link that says "Jump to estimated tax payments." That takes you to the screen that says "Estimates and Other Income Taxes Paid." Scroll down a little to the second section, "Payments with Extension." Click the Start or Update button for Payment with 2023 federal extension. The payment will appear on Schedule 3, line 10, and will be subtracted from the amount that you owe.
If you need further help, tell us whether you are using TurboTax Online or the CD/Download TurboTax software.
