Here's the bottom line.
If you received a 1099-NEC with income reported in box 1, then as far as the IRS is concerned you earned that money while self-employed and "in business" for yourself. Understand that one does not have to "own" a business, to be considered "in" business. Your comment, "I do it personally" further confirms that you are in fact, in business for yourself in the process of earning that income, as far as the IRS is concerned.
That 1099-NEC income will be reported on SCH C as a part of your personal 1040 tax return. Note that in the SCH C section of the program you will also be able to deduct from that business income, any qualified business expenses you may have incurred in the process of "doing it yourself".
