Yeah I figured out the ME - Ref #60159 but the way they worded it was not specific. You have to read between the lines and have a good working knowledge of proconnect. 

i.e. the diagnostic said that you couldn't e-file when K-1 withholdings on line 15 doesn't match state & local: other credits but I didn't have anything on the the other credits. So I took the withholdings on line 15 off and entered it on other credits and the diagnostic went away. woohoo. Actually I entered the K-1 withholdings on the 1099-Misc screen. That's a new trick I recently learnt.
