I left a company and returned to a different location under a different ein number. how do I file both id numbers with the same parent company?

If your W-2's have different EIN's for the employer on each of them, then you will be able to enter both W-2's separately on your tax return.  Simply select to "add another W-2" in TurboTax.

1. Sign in and open your return if you don't already have it open.
2. Select the search icon at the top of the page and search for W-2 and select the Jump to link.
3. Select Work on my W-2 now and Continue.
   1. If you've already entered a W-2, select the Add another W-2 button.
