How do I go back to edit federal return? There is no Federal Tab on the Left?

Have you already transmitted your return? If so, you will be unable to edit the return until the IRS either accepts or rejects it.

If rejected, you can make your changes or add information to your return.  

If accepted, you would need to amend your return to correct or add information to your return.

My return was rejected yesterday 2/19/2020.  I have not been able to find a way to correct the error.  Reject number is Fw2-503.  I have correct Fed ID Number. Can not find returns for correction. Cannot even find  completed returns.  Please help.

Sign in to TurboTax, select Fix my return, and follow the instructions. Make sure your are signing in with the same User ID.
