T4 Insurance non-taxable vs Quebec Insurance taxable - how to edit

SUGGESTED

Hello,

I'm trying to fix an issue with my group insurance for some employees. Essentially, it is taxable in Quebec, but it is non-taxable on the T4s. The amount still shows up in taxable income for the employee on the T4s, which shouldn't be the case.

Each year I run into the same problem where I send amendments but the government sends me more paperwork.

I was wondering on how I could setup the group insurance on Sage to remain in the taxable income on the provincial documents, but to be deducted from the federal side. 

If I can't retroactively do it for 2022 taxes, I'd like to set it up for 2023 so I don't into the same issue next January.

Thank you for your help!
