Business & farm

I am getting the same rejection error.  I have a consulting business and do not have any inventory.  My 2019 return shows no inventory at the beginning and end of 2019.  My 2020 return shows no inventory at the beginning and end of 2020.  However, my 2019 return does have an entry for "Cost of Labor" brought over from QuickBooks.  This labor cost did not produce an entry in the 2019 beginning or end of year inventory.  Is it possible there is a "glitch" that is causing some to think there is an inventory discrepancy?   If so, is there a fix?  Or, do I just mail a paper return?  Thanks for any help.
