Business & farm

You can enter a 1099NEC multiple places. You need to delete all that you have entered. Go to the business section of the program, enter your business information as a Door Dash person. See Where do I enter Schedule C?

Once you get past the profile, it will ask about income. Select the NEC there and enter the information as part of the business return. It is the first option. 

In addition, see IRS Gig Economy Tax Center for more deductions.
