When you start your Sch that came over from 2019 - it should ask you if you have these 1099's - 1099M or 1099NEC? I walked a customer through this the other day, because her 1099nec's were not linking to the Sch c from last year. We deleted the Sch c info and started over. That's when I saw that it gives you a choice of "did you have a 1099M for "xyz" company or a 1099NEC for "xyz" company?" for 2020. Then you pick which one you have for 2020. If you had a 1099M for 2019, you should now have the choice of a 1099M OR a 1099NEC for that company and you pick the one you want and then the other one will be deleted.
