ESPP Sale

I'm trying to enter sale information on my 2020 TurboTax return related to a stock sale from an Employee Stock Purchase Plan (ESPP).  I entered all of the required information, including information from forms 1099B and 3922.  After I get the information entered, the program is showing "20 shares of Not employer stock" with a cost basis of $0.  I've entered ESPP sales in past years on Turbo Tax without this issue.  I can't figure out what is wrong.
