Solved
I've added this info on my Turbo Tax, but it is now asking "Select the business that generated this income or add a new business. I did this as an individual, not as a business.
The work you did that generated the 1099-NEC was contract work. That means that you weren't an "employee" of the folks you did the work for.
That said, you are considered self-employed for this income. Your "business" is you. You can use your SSN to identify yourself. You'll be required to pay self-employment tax on income over $400. Income tax will be owed on all of the income, as well.
TurboTax will generate the proper forms for your filing. The FAQ I'm linking below will explain in more detail.
