Yes, schedule C.

The actual law 1099-MISC was over $600 but no matter, some businesses reported everything, even sums well under that. If there's a 1099, the IRS has a record.

The former version of the "K" (1) the amount that would otherwise be reported exceeds $20,000, and (2) the aggregate number of transactions exceeds 200.  The new law replaces this two-step de minimis standard with a single $600 reporting threshold effective for 2022.  Accordingly, a single transaction for more than $600 settled through a TPSO will now be reportable as will multiple transactions that total more than $600.

This isn't all. 1099-NEC for independent contractors, will ask that anyone making payments, tells Big Brother, so they can tax us. This was a minor loophole where paying someone for "expenses" is not reported as income. Kind of like paying cash, to avoid taxes.

Party politics aside, this is what comes from tax and spend economics. The money that is handed out has to come from someone else, or somewhere? You and everyone who worked under the old rules, $20,000 and 200 transactions has now felt the current group in power, reach into your pocket and remove money from your wallet. The name is interesting? "American Rescue Plan Act" which is the answer to how the government will pay for all the Covid-19 stimulus checks.

Free lunch isn't free and neither is the free money that was sent out.

From the text below from wikipedia I understand that only paypal will issue a 1099k in this case so there will be no double reporting, and thus no double taxation.
"the instructions for Form 1099-MISC include a provision that says payments made with payment cards and/or third party network transactions must be reported on Form 1099-K by the payment settlement entity, and that the payer does not need to issue a Form 1099-MISC in this case"

Quite a mess, isn't it? Simple answer is still, Schedule C so the income balances, which avoids the red flags and inquiries, if someplace does issue duplicate reports of income to the IRS.

1099-NEC is used report nonemployee compensation. "The IRS has reintroduced Form 1099-NEC as the new way to report self-employment income instead of Form 1099-MISC as traditionally had been used. This was done to help clarify the separate filing deadlines on Form 1099-MISC and the new 1099-NEC form will be used starting with the 2020 tax year."

So I don't know if some people will run into problems with double reporting as one form will come from Paypal and another from the agency. Good to be ahead of this, instead of being a surprise in 2021 when it's time to file.
