Insofar as I know Proseries does not and has never supported North Carolina partnership efile.  It does support individual and corporations (S and C) efile.  I have no idea why.  NCDOR refers me to Proseries and Proseries has no place to call to ask.  Their customer support sucks and they have morons answering your questions as to how to use the software.  I spoke to a moron to day.  I call on Proseries users from NC to post to this board to complain about their lack of NC partnership efile.
