Since you describe this activity as being an "Independent Contractor", you should report the income as sell employment.
You do not need a 1099.
In TurboTax (TT), enter at:
- Federal Taxes tab
- Wages & Income
Scroll down to:
- Business Items
- Business Income & Expenses (Sch C)
You will have to pay Self employment tax (about 14.1%) in addition to income tax. "Self employment tax" (SET) is how you pay social security & Medicare tax, on earned income when none was withheld.
If this was a one time gig, you may be able to avoid SET by reporting it as "other income". See https://ttlc.intuit.com/community/taxes/discussion/re-1099-nec/01/2217598#M797656
