Selected Self Employed and don't need it now. How do I go back to Basic?

You can downgrade your version of TurboTax Online by using the Clear and Start Over option.  This will clear everything from the return and you can start over using the version that you want.

Note: In TurboTax Online, you can clear and start over as long as you haven't paid or registered yet (free users are asked to register their accounts before they file).
