In TurboTax, we don’t create a separate entry for your 1099-K info. That's because your 1099-K income should already be included in other income, such as your total self-employment or rental income, such as a 1099-MISC.
Just be sure your self-employment or rental income includes your 1099-K info. You can enter this in the "Self Employment" or "Other Common Income" sections under "Wages and Income"
