How to manually correct form? dividends not loading properly in MA state tax form. (schedule B line 6b miscalculation)

Filing as a part-year resident. Dividends earned while in MA but treated as out-of state and not taxed. (not included in schedule-B line 6 statement: Part-year Resident Excludable Interest and Dividends Line-B, which only included allocated interests but not dividends).

Thanks!

p.s. 
Confirmed that federal and other state (NY) allocations are correct.
