I just know that the 2 forms are connected and when you input the information from the T4 and RL 1 the schedule 8 is created, it's not a question of completing the schedule 8 separately as was suggested in another post.
It's looks like we are having the exact same issue.
I'm also in Quebec and entered the information from the T4 and RL 1 in the system.
For the T4 I entered the data in box 17 for QPP contributions .
Line 30800 on the T1 is empty which should be populated and there is no line 50310 on the schedule 8 as is required.
