When I look at my unrecaptured section 1250 worksheet there is a value on line 18 of $248 and it says this value should be entered on Schedule D line 19. When I look at Schedule D line 19 the value shown is $0. When I try to override the $0 value with $248, there is a worksheet error message with a red exclamation point and the program will not use the override value in the calculations. Is this a bug in the program or am I missing something?

Well, I found the reason after some trial & error. If line 16 on Schedule D is $0 or a loss, the program skips lines 17 through 20 or 21 and zeros them out. I had a loss on line 16 as it were, and when I tried to enter a value in line 19, it gave me the error. I know now that Section 1250 gains are offset by long term capital losses 😉 Learning the hard way I guess...
