Was this as an Independent Contractor? Did you receive 1099-NEC? If the jobs are vastly different from each other, you would need a Schedule C for each.
If so, you would enter your income on Schedule C. Enter the 1099 income separate from any non-1099 income (cash).
We'll automatically complete Schedule C for you when you set up your self-employment work or income in TurboTax, which is usually reported on Form 1099-NEC or 1099-MISC. It gets attached to your Form 1040 which we'll also handle for you.
To set up your business:
If you did not receive any 1099-NECs, then report your self-employment income on Schedule C in the Other Self-Employment Income section. See below.
