The federal does not tax state and local dividends so they are not included on lines 1a,b,c.
Line 4 with the reason codes is only used for income from line 1 that is not taxable to NH.
I also entered income in box 12 of 1099-DIV and it does not appear on the DP-10. Your form sounds correct. See DP-10 instructions here.
