I NEED TO FILE MORE THAN ONE TAX RETURN HOW DO I DO IT

Do you mean your own 2020 Federal and state?  Or several 2020 ones for family members?  Or 2019 and 2020? Or a business return plus a personal one?

To create a second or subsequent return in TurboTax, go to the File menu and select New Tax Return.  If you need to file in more than one state, go to the State Taxes tab, click Continue, and click on Get Another State.
