If you don't need all of the features of TurboTax Self Employed, you can downgrade from TurboTax
Self Employed to the Federal Free or another version of TurboTax Online, as long as you haven't paid yet (or
registered in a free version) - but please bear in mind that
you will need to clear any data which you have entered, and start over in the other TurboTax version. This is the only available method to downgrade versions.
Please see
the following TurboTax FAQ,
"Can I switch to a lower-priced version of TurboTax
Online?":
