Hey there, floatflyer.
Thanks for joining us here in the QuickBooks Community! I'd be happy to point you in the right direction.
Making sure the calculations for payroll deductions are correct is important, I recommend reviewing the calculations according to the CRA. If you are still seeing a discrepancy, you'll need to reach out to the support team outside of the Community so they can take a closer look at what might be happening by doing a screenshare with you. You can reach them by following these steps:
Schedule a Callback: click (?)Help in the upper right > type and enter "Contact support" into the QB Assistant > click Contact Us > explain your situation > click Let's Talk > choose Get a callback.
If you have any other questions, feel free to reach back out here.
