Sorry about that, you're correct that after you've filed it's a little bit different process to get into your return to get the diagnostic file.
When you log into your account, on your tax home page please scroll down to Your tax returns and documents. You can open your return but clicking on Add a state or Amend using TurboTax Online. You don't need to actually amend the return or add a state return, this will just open up the return so you can access your Tax Tools. After you get the return open, you can follow the instructions above to send your file to us and get a token.
