Seems that other people have the same problem and Intuit is looking into the problem, will wait 🙂

Thank you for your question and answer! Yes, it is unclear where the problem stems from, CRA or TurboTax. We will update as soon as possible.

Thank you for choosing TurboTax

This error message goes back years - still waiting

Did you update your software? That message should not appear.

Still happening for a 2024 return I am trying to file in Oct 2025

Getting the same error as well - filing a 2024 return 

I'm getting the same error filing a 2024 return this evening. I tried twice and both failed.

I rebooted my laptop and tried again, and then it worked. Who knows what the problem was...
