I didn’t file my 2021 1099 form how do I add it to this year return

You cannot add a 2021 tax document to a 2022 tax return.   That is not allowed.   If you filed a 2021 tax return without one of your documents then you need to amend your 2021 return.

Only certain paid tax pros can still e-file past year amended returns. You cannot e-file an amended return that you prepared yourself using TurboTax.  Your 1040X must be printed, signed and dated in ink, and then you need to mail it in.  Use a mailing service like certified mail so you will know the IRS received it, since you will have a long wait for it to be processed.

 

 

Even during “normal” times it takes about four months for the IRS to process an amended return.  During the pandemic and due to the severe backlog at the IRS it is taking much longer—six to nine  months or more for many amended returns.  Do not expect quick results from amending.  When the IRS issues a refund for an amended return it will be by check.  They do not make direct deposits for refunds for amended returns.  You can watch for information here:
