Schedule 3 is still locked by CRA and not finalized yet by CRA. Please refer to this link Why does TurboTax say my forms are locked or haven't been finalized? 

We do not have any ETA on this yet but as soon a these forms gets finalize we will be updating them in TurboTax for an accurate calculations.

We appreciate your patience.

Thank you for choosing TurboTax

I understand the Schedule 3 at the CRA is locked, but why can't we print a return for mailing a submission while we wait?  

@Need_To_Know Schedule 3 will be updated, and all the locked forms will be unlocked and ready by the 20th of March, 2025. You will be able to print/Netfile then. We appreciate your patience.

UPDATE: All forms for 2024 are unlocked.
