What form to use, I presented as a contractor once last year and was paid. It is not a business, just a onetime thing.

It was $500 and I know the income was reported to the IRS, I am not sure if I should expect a form from them or if this is something I just have to report myself. It looks like 1099 or 1099 misc. might be my best guess.

Whether or not you get a form report it as Other Income since it was a one time thing.

As the amount is less than $600, you will not receive a form 1099-NEC or 1099-MISC from the principal, but you still have to report this income on your tax return.

If this a "one time thing" with no intention of making a profit, then this amount can be reported as Other reportable income.
