From my understanding, it's a TurboTax issue, it's not generating the return properly. I had the same issue, it let me file QC but not CRA with the same error code. I made an entirely new tax return with TurboTax and the exact same thing happened again. I tried Wealthsimple and it worked. I'd suggest trying them if you can. It seems TurboTax doesn't care about this, it's been happening since February. I found this old thread where the admins responses are kind of hilarious but depressing: https://turbotax.community.intuit.ca/community/troubleshooting/discussion/cra-result-code-84-95033/0...
