when you paid with your request for extension of time, you put that amount on your tax return for a credit.

State and/or Federal.

enter under "estimated tax payments".

@fanfare The user states that they did not use TurboTax to file the extension request--so nothing went on the tax return when they sent the 4868.   They need to enter it now.

xmasbaby0: Thanks. I just entered the $450 and $750 in the current Turbo tax filing and now it is showing me the money that's due from IRS and VA. Thanks so much!!!

I sent a 4868 by mail, with my check for $470. Now am filing my return, which states I owe $454, which I have previously paid. How do I add this info to my electronic return?

If your extension payment did not automatically show up on 1040 you need to enter it. So make sure it's not already there before you enter it!

For 2020 Federal Extension payments should be on schedule 3 line 9. And flows to 1040 line 31.

You can type estimates paid in the search box at the top of your return and click Find and it will give you a link to Jump To the screen where you enter Extension Payments.

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
