Did you use your web browser to create your return? If so, you are using TurboTax Online, not the CD/Download version. If you want to continue with those returns, you will have to pay again, because the CD/Download will not work with the online version. In that case, you can request a refund for the CD/Download version here: https://turbotax.community.intuit.ca/community/after-you-file-questions/help/how-do-i-get-a-refund-for-a-turbotax-product/00/873559
If you would rather start again using the CD/Download version, you can download it from our website here: https://turbotax.community.intuit.ca/community/product-information/help/where-can-i-download-the-cd-download-edition-of-turbotax/00/873703 When you install it, it will ask you for your code then, and you will not have to pay again.
