You will need to add your second W-2 to the first filing only.
To add your 2nd W-2, it depends on the status of the first filing.
If it has been accepted and approved, then amend(change) the return that was filed.
- Get started on the change, but wait another few weeks until Form 1040-X is available to actually file.
- To do this in TurboTax, open the first account that has the first W-2.
- If you had added the W-2 after filing, return to this area and delete it.
- From Tax Home, scroll down to Your tax returns & documents and Show More.
- Go to 2020 and select Amend(change) the return.
- This must be selected before any changes are made to the filed return so that Form 1040-X shows what was filed first, the change, and what is filed now.
- Next, return to the Jobs(W-2) section and add your 2nd W-2.
Only if the first return was not yet filed, then directly add the W-2 and try e-filing again. Form 1040-X will not be needed. The change can be done without waiting.
- Inside TurboTax, go to the search box and enter W-2 and select the Jump to link in the search results to return to this area of your return.
- Look toward the lower left hand side of Your W-2 info so far and select Add a W-2.
