Do we really have any evidence that what print's with the filing copy has anything to do with what is transmitted.

You can select almost anything you wish to print with the filing copy, or deselect the forms as well.

I print the diagnostic's and a bunch of worksheets with the filing copy, as that is the way I set it up in the print options, and I sincerely doubt that all of that is formatted to transmit with the return.

The default's in the filing copy, are (more than likely) just some programmers guess of what most of us would print if we were mailing in a return, and based on Intuit's programming record this year, I would not be placing bets on that.

Now if you want to say "All of the IRS Forms that print with the filing copy" I might go with that, but I am pretty sure that the detail information for W-2's, 1099-R etc. also gets transmitted, and I have  not seen that printing with the filing copy.

TO BE CLEAR. I do not know what transmits with the returns, as I have not found a way to find or look at a transmit file from proseries that is formatted to the IRS parameters, but I don't think it relates very well to what is called the "filing copy" when we are determining which copy to print.
