Did you go to turbotax.ca/activate to use your code before you started your returns? You can see this TurboTax FAQ for step-by-step instructions: In TurboTax Online, how do I use a prepayment code?
Yes, I put in the activation code via the activate web page as per the instructions.
When I log in it shows that I have 8 returns available. it shows the deluxe turbo tax that I purchased. I just find it strange that when I started doing my returns it was telling me how much each individual return would cost. Maybe when I file it will not try and charge me ? I do not know. Help line is not available today to call so I guess I will have to wait until next week when I file to find out what happens....or be able to call support.
