What to do about wrong 1099s?

I am a freelancer and I received over $600 from several customers during 2020.  It seems that everyone is confused about the 1099s.  Instead of sending the 1099NEC, they are sending me 1099misc with an amount in box 3?  Do I need to get all of my customers to send the 1099nec or can I go ahead and file with the 1099misc?
