I am filing taxes in Quebec for the first time but it will not let me file without a 2016 or 2017 Quebec notice of assessment number?

When I was filling out my return, I answered that this was my first time filing in Quebec but it still asks me for a Quebec notice of assessment number, and it will not let me move forward without entering one (which I obviously do not have). I tried answering that I need to sign up for Revenu Quebec and entering my other information (like banking) but that didn't work and then I tried calling Revenu Quebec to do that over the phone and clicking that I am already signed up for Revenu Quebec but no matter what options I choose it prompts me to enter my notice of assessment number.
