Retirement tax questions

@ThomasM125 

I have a similar situation.  I received a w-2 from my employer and I did a small amount of contract work and received a 1099-NEC.  I don't understand why it is saying I need a 3801 form??!?  I don't own a business... Just did a side job.  Do I just delete the schedule C form (like I believe user @Marge2 did?? Please help, so I can file my state taxes!
