Turbotax deluxe not for free?!

I downloaded the turbotax app and followed the instructions to enter the informations needed. However, being done so I go to my bank account and see that the app has been purchased! They didn’t even ask for my credit/debit card number. How is the app purchased without even giving me a notice about it? They only asked me if I want to add extra 50$ for MAX and I said no, but even the deluxe it wasn’t stated that i had to purchase it. How can I stop this? Can I get my money back?
