I have been led to believe that the only preparer added statement that gets transmitted is "Preparer Notes"

I am sure that in my case the "filing copy" has nothing to do with what gets transmitted, as I have for years edited which forms print to fit my wishes, as I use that copy exclusively, and make copies of appropriate pages as need for other copies, but I don't know if you leave that in defaults if that means anything regarding what gets transmitted or not. I just have not found anything authoritive to rely on for an absolute answer.
