The T1198 form is still locked by CRA and not finalized by CRA yet. 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 as these forms get finalized, we will be updating them in TurboTax for accurate calculations.

We appreciate your patience.

Thank you for choosing TurboTax.
