Opening a new tax return should work - use the “FILE” menu, then "OPEN NEW RETURN” menu item, press “SAVE” for the existing return (if needed) & then “START A NEW TAX RETURN". In easy-step mode, I had to start all over, with the personal information like you’d expect & that is the first indication that you have started a completely new return. I just used TT Business for both a partnership Business return (1065) and then a separate Estate Return (1041). It worked fine for both.
