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

Unfortunately, you cannot use the 21 digit Installation Key Code (IKC) you have for the CD/Download version of TurboTax. As you purchased your copy at a retail outlet, you can request a refund for that purchase, and then you would need to pay for your Online version after you complete the return.
