Can I convert home, business, rental property data to deluxe

Can I convert home, business, rental property data to deluxe. I originally had deluxe and don't know why updated to home, business, rental property last year, would like to go back to deluxe because of price. Can I convert back to deluxe? Unless there is a way to get rid of nasty expired membership banner(I'm very displeased with this as it did not say this would happen only that online functions would not work, Which I don't use) I would not have updated if I was warned
