Fed refund received, state still showing incomplete and all forms are available. "Cannot be filed"stamped on top of state tax forms, so need to reprint to mail.

UPDATED FOR TAX YEAR 2019

Your state return(s) will show a status of incomplete if you filed your federal return by itself (or with another state).  If your federal return has been accepted you can e-file your state return.  

Follow these steps to e-file your state return once the federal return has been accepted: 

1. Sign back in to your TurboTax account.  You will be on your Tax Home screen.
2. Scroll down to the 2019 menu towards the bottom of the screen.
3. Click on the Add a State box at the bottom of the screen.   [Don't worry, we're not really adding a state, this is just a way to re-enter your return since the federal return has been filed and accepted.]
4. If you not completed your state return, click on the State Taxes tab.  If you have completed your state return, click on the File tab and go through the prompts to file your state return.
