I have been trying to file a return that has a NOL carryover from 2018.  The return keeps rejecting , the error code is F1040-33.  It says I need to attach "Other Income Type Statement", I have  the NOL Explanation Statement in the return.  It states that if Form 1040, line 21 Other Income includes an amount for a NOL, then the NOL explanation statement must be attached to return.  Line 21 is not Other Income on the 1040, cant figure out what it is referring to.
