No - if you don't need all of the features of TurboTax Self Employed, the only way to downgrade, to another version of TurboTax Online, is to clear any data which you have entered in Self employed, and start over in the other TurboTax version...and this can only be done if
you haven't paid yet (or registered in a free version)
Please see
the following TurboTax FAQ,
"Can I switch to a lower-priced version of TurboTax
Online?":
