@brnsdv we understand your frustration and we apologize for the inconvenient.
We suggest you to visit this link from CRA.
As my colleague explained, they are working to update the Schedule 3, related to your T3. This means, all forms related to, including the entire Schedule 3 and the split with your spouse, can have some wrong calculations. Some of these forms are completely locked.
Thank you for choosing TurboTax.
