By "revised" do you mean you need to amend your 2021 return? If your 2021 return was filed and processed by the IRS, you can make changes by amending the return using a Form 1040X, which will have to be sent in by mail. It cannot be e-filed. Expect it to take four or five months to be processed. Mail it using a service like certified mail so you will know it was received.

Do not expect quick results from amending. It can take four months or more for the IRS to process an amended return.
