After you file

Yes, you should include a copy of your W-2 if you are mailing in your tax return.

However, since your federal return was e-filed you should still be able to e-file your state return. To get back into your state return please take the steps below.

1. Login to your TurboTax account.
2. In the Welcome Home box, click Visit My Tax Timeline at the bottom.
3. In the SOME THINGS YOU CAN DO section, click Add a state.
   
4. Click on the State Taxes tab.
5. Click Continue to start or complete your state taxes.
6. Click Done with State.
7. Continue through the flow to review and file your state taxes. Make sure to change your filing method to e-file instead of file by mail.
