All sales reported on a 1099-B from the broker must be reported even if the sale was also reported on the W-2 and if the 1099-B doesn't have the cost basis listed correctly then you must enter the correct amount yourself. Usually these sales will show a loss in the amount of the broker's fee for the sale.
If this is on a 2019 return then the IRS will be sending you a CP2000 for the missing "income" soon so getting ahead of the action is wise so you will need to AMEND the 2019 return which cannot be done on the 2021 program.
