How many returns did you complete? If you purchased TurboTax Online from Costco, you would need to activate your code here at turbotax.ca/activate before you start any returns in order for them to be completed under the software that you purchased.
It seems as though you may have completed 2 returns using TurboTax Premier which are $34.99 per return- therefore if you did a joint return it would charge your $34.99x2. (The reason you didn't get charged the difference between Deluxe and Premier is because you never activated your code before completing your returns.
Thank you for choosing TurboTax.
