- Search for W-2 and select the Jump to link in the search results
- On the Your W-2 info so far screen, select Add another W-2
- Enter the information from the new W-2 on the following screens
If you already e-filed, you'll have to wait until your return is either accepted or rejected.
- If rejected, you can add the W-2 as previously described before resubmitting or paper-filing your return
- If accepted (or if you already paper-filed), you'll need to amend your return to add another W-2
