where to input tax extension and amount paid tax with extension

[huiwen]

I filed extension through FreeTaxUSA and pre-paid Federal tax while sending extension. Now where could I input this amount in Turbotax? How to prove my extension in Turbotax?

To enter the amount you paid with an extension (including state extension) go to

Federal Taxes (or Personal for desktop H&B version)

Deductions and Credits

Then scroll way down to Estimates and Other Taxes Paid

Other Income Taxes - Click the Start or Update button

Next page second section Payments with Extension

Either Visit All or Click Start or Update by the extension you paid

For 2023 Federal Extension payments should be on schedule 3 line 10. And go to 1040 line 31.

You do not have to "prove" your extension to TurboTax.  There is no place to indicate on the tax form that you have an extension.  The IRS knows, though.  So file normally, and just make sure to indicate the payment you made when you requested the extension, as VolvoGirl instructed you to.
