Big Problem.  Client Trust 1041 return has a long term capital loss carryover from 2017.  On the 2018 return - Schedule D, line 15 - long-term capital loss carryover is the correct amount.  However page 2 Schedule D, PART III, line 18c has a number for 28% rate gain, pulling from a 28% Rate Gain Worksheet -- WHICH IS COMPLETELY WRONG. There was zero 28% rate gain from 2017 or 2018.  In fact, the Total, Line 19 for Schedule D, PART III, doesn't even add up correctly - it is ignoring the wrong number on 18c --  Don't think IRS will ignore a gain amount.   

Disappointed that even the mathematical error was not caught.
