How can I edit my federal and state returns after I printed? I haven't mailed them yet. I'm using Turbo Tax online. Site not letting me get back to editing my returns!

After you choose to Mail in and you print your return, TurboTax thinks you are finished, there will be no  "Take me to my return" button.

To open your return:

1. Log in to your account 
2. Choose "Add a State."  (you don't really add one; that's just to get the return to open up.)
3. Once the return is open, you can choose from the left menu the section that you need to Edit.
