Bottom of the info worksheet.. Part XI.   Do Full year NH resident.. but also check the box to do a NON-Resident for MA.  then QuickZoom to the Non-Resident State allocation.. click on the MA...and then just go down the line and put what should be in MA column.....if not already there.  For instance if he had Sch Income... only put the MA amount in the MA column... you will see it's pretty easy I think.
