Did you get a 1099Misc for something? That is usually for self employment income.
You can try to downgrade to a lower version but you will have to clear and start over.
If you were paid for something in cash, or if you received a 1099-MISC with the income reported in box 3 or 7, then as far as the IRS is concerned it's self-employment income.
For box 3 there are exceptions to treating it as self-employment income. But that does not negate your requirement to report the income anyway.
