Get your taxes done using TurboTax

Yes, I did all that.

I downloaded it on my mom's pc, then i logged in to my account and i saw the code there with the numbers hidden except that last 4 digits and i clicked activate and then got that error 605. It didnt activate.

So what i need to know is if Big Home Tax is a scam seller and these codes were used by someone else they sold to?  I cant get any response from Big Home Tax.
