What do I do if I filed my taxes and received additional W-2’s

You will need to wait until you can amend your tax return in a few weeks. It may delay receiving your taxes. You could also save them and add them to next year’s return.

You cannot save them and add them to next years return.  Income received must be reported in each individual tax year.

If you filed, it is like dropping it into a mailbox - you cannot get it back.

You'll have wait until your return is either accepted or rejected.

• If rejected, you can make any necessary changes.
• If accepted, you'll need to amend your return. 
• To avoid unnecessary delays, do not amend until your original return has been fully processed.  You will need to print and mail the amendment.  
• Allow 8-12 weeks for processing.

See this TurboTax FAQ for help with amending.

You can check the status of your amended return here, but allow 3 weeks after filing for it to show up.
