After you file

@fanfare 

Thanks for your response.

Yes, I did save the revised return, exit Turbotax, and then look again. All of the lines on Form 8606 Part I are blank. On the original return, Form 8606 Part I has entries on all of the relevant lines except for line 6 (due to my mistake of not providing it).

 

I have not filed the revised return.

 

Is it possible for me to use email in communicating with customer support?
