I tutor through an agency, tutorbright, but i'm considered an independent contractor through them. How do I report my earnings for this?

Did you receive a 1099-NEC? This is for non-employee compensation.  You will enter this as self employment income.  You will need to file a Schedule C and pay SE taxes.  You may also enter any expenses related to your work to reduce your income. 

To file a Schedule C, here are the steps:

1. Sign in to your account and select Pick up where you left off
2. At the right upper corner, in the search box, type in schedule C and Enter 
3. Select Jump to schedule C 
4. Follow prompts.
