Did you upgrade from Deluxe and ended up in the Premium Edition? If so, did you try the steps in this FAQ to downgrade? If so, where is the roadblock?
FAQ: How do I downgrade to a different TurboTax Online product?
Or do you mean you added "Premium Services"; i.e., are you a California filer who chose to pay your TurboTax product fees out of your Federal refund? If so, in California that payment option adds Premium Services. If that's what you mean, we can tell you how to remove that payment method and pay upfront with credit/debit card.
Those steps did not work. It will only let me downgrade to FREE, but I want to go back to Deluxe.

I don't know why it won't let you. In any case, if you wish, you can try downgrading to Free Edition and then upgrade that to Deluxe. Or, as mentioned in that FAQ, you can use "Clear and Start over" and choose Deluxe from square one, but you have to re-enter everything. Be aware that Online Deluxe cannot handle Schedule D (capital gains/losses from stocks/bonds/mutual funds, etc.), Schedule E (rental/royalty income), Schedule C (self-employed business), and cannot enter a K-1.
Or you can phone TurboTax Support for guidance. Support hours are 5AM-9PM Pacific, every day this time of year.
