I have the same issue with the rejection of my federal and state returns for the same error message (An XML document that represents a binary attachment ...) and contacted Intuit for assistance. They said that the problem was probably most likely with my 1099NEC's having some unacceptable characters in the filers name [&,#, etc). I went through my 1099NEC's and made a correction to one and double checked everything. I refiled and was again rejected by the IRS and the state. I do have a form 7206 in my return also (which I need) and think that this is now the problem. It appear to be OK, but how do I know what's acceptable to the IRS. Has anyone tried completely deleting their Sch C and 7206 and recreating them? I don't know if this would recreate an acceptable Form 7206.
