Enter as Less Common Income and chose the last option Miscellaneous income. It is not a check, it is a 1099K. TurboTax does not say 1099K for Less Common Income, but it is still the correct place to put it. Next year there will be more guidance and probably a special section to enter this type of 1099K because so many more people will receive it for 2022, due to tax law change.
