changing package prior to payment

I'd like to revert to the Deluxe package, but I can't find a way to do so.  I have not paid yet and am not going to use Assist and Review Deluxe to file, but I can't find any way to update this.  I tried starting a new return, but then I would need to re-enter all the data that was not imported from 2022's return, and I'd rather not rebuild my return!
