The most recent thread I can find on this subject through this amazingly awful search feature was from last year and the answer given was if it is in the filing copy then it is transmitted.  But when I asked customer service that question last year, I got a definitive "not sure".  So I attached a word doc as a pdf, knowing that the attachment was transmitted.

I of course can do that again this year.  But it is easier to just do it through the program.  So does anyone know with certainty if I see it in the filing copy then it will be transmitted to IRS?

Thanks in advance.
