What is the exact error message that you are getting?

 

I message pops up tell me that CRA hasn't finished their forms to keep looking for update before filing.

CRA site say that you can start filing as of the 24th that would mean the forms are done.

@Ddean44 We're working hard to finalize these forms to align ourselves with CRA requirements, and we hope to have them ready soon. We appreciate your patience.

You can see a list of Forms that still locked here: Why does TurboTax say my forms are locked or haven't been finalized?
