Uncertain of what you mean by "locked Netfile" account - if you are unable to access your MyCRA account then you would have to contact the CRA. If you are getting a Netfile error while attempting to file your tax return then you would contact our support team for assistance.

Here is the message I get when I try to Netfile, CRA says TurboTax has to unlock it from your end:

I got the same issue. Do you know how to unlock it?

This is a message from the CRA as they are the ones responsible for the NetFile- As per the CRA: The link given shows: We are unable to complete your request at this time. If you need to reach us please try our toll free number at 1-800-959-8281.

Thank you for choosing TurboTax.
