Which Turbo Tax Section: Amazon Flex, Doordash, Mercari, Offer Up, and 1099 Job

Hello,

I'm wondering which section on Turbo Tax I file the below information.

In 2021 I earned money via:

  • Amazon Flex
  • Doordash
  • Mercari
  • Construction Worker (1099)
  1. The company I worked as a construction worker for did not provide a 1099 but I only worked for 3 days and I know the gross amount I made. Which section and how should I report this information?
