I'm having problems on how to report my income on Schedule C. I received my W-2 from my employer for 2020. Due to Covid-19, I worked from home the entire year.

If you received a form W-2, you are an employee and you are not self-employed. You do not report your income from your W-2 on Schedule C. You report the form W-2 under the Wages section.

The previous reply is correct unless the W-2 is marked as a Statutory Employee, which is highly unlikely.

The fact that you worked at home has no bearing on how you would report your income. As a w-2 employee, there is no longer a deduction for home office.
