Do you live outside of Quebec but work there? Are you using TurboTax CD/Download or TurboTax Online?

Yes, I live in Ontario but work in Quebec. I am using Turbo Tax Premier Online Edition.

The amount in Box J of the RL-1 slip is for Quebec purposes only. These Private Health Plan contributions are not taxable for federal purposes, which is why they don't appear on the T4 slip.

They are however a medical expense if included in employment income. In the past, Turbo Tax allowed the full entry of the Releve1 which thereby allowed the inclusion of the Box J as part of income. Is there not a way that I can enter the full Releve 1 info?

No, there is no way to enter the full Releve1 if you don't live in Quebec. 

You can enter the health insurance premiums in the Medical Expenses part of the return.

Thanks, I am aware of that. My challenge is to enter the Box J amount as part of Employment Income.

Again, the health insurance premiums are not taxable on the federal level, so you would end up paying tax on something that shouldn't be taxed.

Also, if you change your T4, the CRA would likely just change it back, since it doesn't match the T4 that they have on file.

If you think that there is something incorrect on your T4 slip, then you can contact your employer to verify if that is the case. Then they can get you a corrected slip if needed.

It's in Box 85 at the bottom of the T4 slip (added as a custom box by your employer).  The amount in box 85 does not match with box J on the Releve 1. I don't know why, I'm guessing the full amount is not claimable on the T4 (Federally).
