CRA told me to report a bug in Turbotax Business Incorporated 2021. Unfortunately, I spent a lot of time and couldn't report it. There is no Contact Us.

CRA told me Turbotax Business Incorporated 2021 has a bug and it failed to do Part 4 tax, as they found many such errors, including mine. The software did not calculated Part 4 tax, though the data is there.

I need Turbotax Management to take note of this error because it has the data but did not calculate the tax.
