can i use my cd key to fill tax online?

Hello,
So I have previously filed taxes using turbo tax online but this year I bought the cd at Costco. Is it possible complete the taxes online and then enter the cd key to submit the taxes? I bought TT premier and of course i would be using premier online as well.The reason I prefer doing turbo tax online is because I already have a profile, so it will be way faster than filling everything on the cd version.

Thank you
