Thanks for your reply! When following the steps described in the link, there seem to be no location to enter the Relevé 2. This is probably because I am not a Québec Resident. When the income on the T4A/RL-2 was paid I did live in Quebec though, hence why I have this slip.
When going back to the profile section and change my residency to Québec, the instructions provided work perfectly, but that would make me file my taxes in Quebec. Having moved to another province this year and having to file in this new province, I can't find where to enter the Relevé 2. Any idea?
