Hello, your W2 wages will flow directly to form 1040. As an independent contractor you will report self employed income on Schedule C. Once reported on Schedule C, you will also see this info flow to your form 1040. You may or may not receive a 100NEC for work performed. If you do not receive a 1099NEC, you are still required to report all income earned.
