Statutory Employee

I don't have ANY W2, only W2G (gambling). It keeps telling me on a W2 I entered, which I never entered any W2s, that I am a Statutory Employee.  I know that if I did enter a W2 it would be Box 13 that's checked, but I have no W2 hence no box 13 has been checked. I'm self employed, sole proprietary.  It will not let me file without correcting this.
