ALL of us are hoping and praying that TTX can fix that ridiculous software error by the end of the year...months ago would have been appropriate, but they don't seem to be able to do anything about it now...
you can download another copy of your "filed" tax return (the one you actually filed) by doing the following.
Log back into your account.
go to your 2016 "Timeline".
Select "Add a state" from the "Some things you can do" menu. (No, you won't have to add one)
....once inside your 2016 tax file, go to the top of the screen to MyAccount and download a new copy from the "Print Center"
That should be the correct one.
The same thing can happen for those people who "Amend" their tax return...sometimes they have to use the same process to re-download their proper amended forms.
One other thing to try...log into your account.
go to the upper left corner and click on "My TurboTax".
There is a dropdown with "My Docs" as one.....select that.
See what PDF is in there. (do a "SaveAs" so that it doesn't overwrite your good one)
