I signed up for Turbo Tax Deluxe only and my order payment says I am paying for MAX Defend and Restore also. Why????

Apparently you clicked the box to purchase that when it was offered.

I just had the same experience. I am very upset and don't trust Turbo Tax anymore.  I signed up for the Deluxe and was billed for Max.  I submitted my card to pay the state taxes and instead, Turbo tax took their fee first without letting me know how much their fee would be.  My bill should've been $120 and they charged $250.42.
