The form does not take into account that one number is negative ...unless that's what it's supposed to be..instructions just say 'total'

I am not sure I understand what you are asking.

Are you talking about Arizona form 140 for full time residents? Are you suggesting that line 19 and 20 are supposed to be combined and the "sum" put into line 21?

The Instructions say that line 21 is equal to the total amount of net long-term capital gain or (loss) reported on federal Schedule D, not any combination of lines 19 and 20.

Actually, line 19 is the total, it looks like lines 20 and 21 get added together on Schedule D to arrive at line 19.  Please review the instructions here.
