I did not reread your reply by the time I got to printing. Unfortunately, I did not follow your link but only remembered the pay/print/revise sequence. So, I incorrectly, paid and printed the return but could not go back and edit it. I vaguely recall clicking a button "I am done". I am guessing that when that button is pressed, the return cannot be modified. I suggest that TurboTax add a comment at that button like "To print your return and possibly revise it, go to Tools/Printing before pressing "I am done"". That approach seems like an easy add and would make filing (and possibly correcting) the return much easier.
