@raymondavalos - You must have filed for a prior year because the IRS is not accepting amended returns for tax year 2021 yet. However, there is nothing to do but wait and allow IRS to sort through the documents and process. If they are identical, they will only process once. hopefully.
TurboTax does not have the ability to STOP a filing. Once submitted, IRS has total control and all communications should be with the IRS.
Most likely, IRS will pick up the error and not process the second submission.
