Usually Proseries will indicate the form used to back up their figures, like they do for the 1040 program.  I thought I would ask the community, just to see if I was missing something.  I know I can add an expense (plus the $600 exemption) that would bring taxable trust income to zero, but I don't think those have anything to do with how Proseries arrived at zero.

I won't go into much detail here, but I get the feeling that 1041 issues are not as straightforward as 1040 issues.
