Line 13 is capital gain or loss.  Is that what you reported?  If you had a 1099-B with security sales the  you should have had a schedule D.    If you print all forms and worksheets is there a schedule D there?   The 1040 Schedule 1 has a check box next to line 13 that is checked if schedule D is  not required - is it checked?
