Using 2020 W2 for 2021

@Blackbunny2k You misunderstood the EIC lookback and made a big mistake.  You must report the W-2 on the tax return form for the year in which you received the income.  You cannot put a W-2 from some other year on a tax return for 2021.   

The "lookback" was only for the earned income credit.  It allowed you to use the income that was already on your 2019 tax return to get a better EIC for 2020 or 2021, but you were supposed to enter a 2020 W-2 on a 2020 tax return, a 2021 W-2 on a 2021 tax return, etc.   And for 2022 you can only enter a 2022 W-2.   

You will need to file amended returns to fix the ones you messed up.   That return will have to be filed by mail.

Select your tax year for amending instructions:

• 2020

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:

And it sounds like you did not even file 2021.    Or did you?  It is hard to tell from your post.  If you did not file a 2021 return, you can do so using the 2021 W-2.

In order to file a 2021 return you need the CD/download software for 2021.  And you have to file it by mail.

When you mail a tax return, you need to attach any documents showing tax withheld, such as your W-2’s or any 1099’s.  Use a mailing service that will track it, such as UPS or certified mail so you will know the IRS/state received the return.

Federal and state returns must be in separate envelopes and they are mailed to different addresses.  Read the mailing instructions that print with your tax return carefully so you mail them to the right addresses.
