Hello Sietske,

Welcome to QuickBooks Community. The program is designed to help you streamline your work using the powerful features in the program. 

Based on what you've described, I recommend making sure you're using the Canadian version of QuickBooks. If so, I suggest following this article that shows you how to: Prepare and submit T4 slips and T4 Summary in QuickBooks Online. 

Let me know if this info helps. I'll be a message away in case you have other questions.
