Thanks. I think that's probably what I'll have them do, but it just seems like there should be a way to produce something from the software that is more authoritative than the e-file confirmation letter. To be clear, I'm not talking about a paper filing - I'm talking about having a copy of the e-filed return that could be printed out or viewed on a computer screen.

As a tax attorney, tax preparation is only one component of my practice. In other parts of my practice there are a wide variety of documents that we electronically file, with a wide variety of acceptable "signature" requirements, depending on the court or government agency involved. But in every other e-filing situation, I can produce a printable or computer viewable copy of the final document, in the form in which it was sent to the court or agency. I'm wondering why the same thing isn't possible with an e-filed tax return. Or is it possible in principle the PTO software can't do it for some reason?
