How could I file sole proprietor plus eidl

[Gordon Starr]

Last year I hired my son to work for me in the family trade business rehabbing and renting houses. It's a full time endeavor for me and I always filled as a real estate professional with schedule e before. Well now is the time to file and I want to ask. What forms do I need to file as a sole proprietor?  Also will I trigger an audit on myself? We are losing income and I think this might help with the sba eidl app I have in.
