It appears that the issue is that Box C on Form 1310 needs to be checked in order to e-file. But in my case checking Box C would seem to be incorrect since I am the court appointed personal representative (Box B).
@mapsjohn
If you check ANY box other than BOX C you CANNOT efile because you have to attach documents.....either a copy of the court certificate if you checked BOX B or the refund check if you checked BOX A.
