Regarding my question about how to specify what portion of Exempt Int-Div came from North Carolina:
I found how to remove the NC exempt Dividend-Interest from my NC return. In Forms Mode I went to the Form 1099-DIV for the Merrill Lynch data that came in via import. The form says Form 1099-DIV Worksheet. Going down to Box 12 I entered: NC as the resident state ID, then the amount that came from NC. On the next line I entered XX (to indicate all other states) and then the balance of the exempt Div-Int. It then worked its way through correctly to the NC return.
