there is no way to reset your return like that.
the advertised method is to undo changes manually.
Worse, if you open TurboTax with an update and it changes your return, your original return is gone and there is no way to get it back.
The UCE tax law in midstream is an example.
Always make a paper copy of your completed return before or immediately after you file, for your records.
It is best to review the paper copy before file.
I violated my own rule and submitted without printing it first.
Now I see there was an error, fortunately, a minor one..
