Forgot to add estimate tax i submitted for 2021 while filing federal return

The IRS should have your estimated taxes in their database so will add the amount that you paid in estimated taxes in 2021 to your filed tax return.

On the amended return, you can the cancel return by clicking Cancel Amend on the left side of the online program screen. 

Or if you are using the desktop editions see this TurboTax support FAQ for removing the amended return - https://ttlc.intuit.com/community/amending/help/how-do-i-cancel-or-undo-an-amended-return-in-the-turbotax-cd-download-software/00/26316

You should not start an amended return until you have received the federal tax refund or the taxes owed have been paid and the payment processed by the IRS.

If for some reason the IRS does not adjust your tax return for the estimated tax payments then you can amend the return and add the estimated taxes.

To enter, edit or delete estimated taxes paid (Federal, State, Local) -

• Click on Federal Taxes (Personal using Home and Business)
• Click on Deductions and Credits
• Click on I'll choose what I work on (if shown)
• Scroll down to Estimates and Other Taxes Paid
• On Estimates, click on the start or update button

Or enter estimates paid in the Search box located in the upper right of the program screen. Click on Jump to estimates paid

Federal estimated taxes paid are entered on Form 1040 Line 26

if it was indicated that the 2/22 payment was an estimated tax payment for 2021 (the 4th quarter was due 1/17/22) the IRS should catch it and adjust accordingly. do not amend until you see what the IRS does.   

all this depends on how you paid and what you indicated the payment was for.
