Do I need to send in my tax return to the IRS if I filed an extension and paid my taxes due.? Not sure if I need to resend the forms.

Filing an extension means you have asked for more time to file your return. So if have not filed yet you must do so by October 17.

The Extension form 4868 is not your tax return.  If you filled out  your tax return it was not sent with the extension.  You  still need to file the 1040 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 2021 Federal Extension payments should be on schedule 3 line 10. And go 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

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