You said "I didn't use there deluxe service AT ALL." If you never used it, you would not have been prompted to pay for it. You are only asked to pay when you try to print or e-file the tax return. In order to pay for it, you had to have been using it. And why did you pay for it if you didn't use it? You didn't have to pay unless you wanted to print or e-file.
TurboTax never said that Deluxe is free. Only Free Edition is free. If you start off in Free Edition and upgrade to Deluxe, it is no longer free, and that is clearly stated when you upgrade.
