Of course I tried these steps. About 100x. None of them worked. I have been using QuickTax / Turbo Tax for 20+ years so of course I know that you need to Review before you Netfile.
By the way on the Revenu Québec site, there is a list of forms that are locked. The TP80 is not one of them.
This is clearly a problem with Turbo Tax and not with Revenu Québec.
Shame on you, TurboTax.
