Can you please provide more information about your problem? What happens when you click the Refile button? Are you using TurboTax CD/Download or TurboTax Online? Have you already received your notice of assessment?
I am having the same problem - I click the reFILE button and just get a new tab opening with the message "Not Found. Redirecting to https://turbotax.community.intuit.ca/community/canada-english/help/03/en-ca". I can't see any obvious way around this, and I can't edit my existing return in TurboTax. Please help! I received my express NoA from CRA already (but not a "regular" NoA) -- though I don't really see how that affects this error in TurboTax.
