If you are referring to https://www.skipthedishes.com/ then you are a self-employed food delivery person.
This would be similar to people driving for Lyft or Uber, except that you deliver food instead of people.
If you received a 1099-MISC with an amount in box 7, then you are considered "self-employed". As such, while you are your own boss, you also have to report all income and expenses, and pay federal income tax and self-employment taxes on your net income from your business.
If you are looking for a principal business code for your Schedule C, use 722300 (Special food services (including food service contractors & caterers)).
