Hi there,
Welcome to the Community. I'm glad to learn you're using the QuickBooks mobile app to help streamline your work. I'll be happy to share more info so you're on the right track.
The ability to run payroll isn't available on the mobile app. I recommend using the web-browser by visiting and signing into https://quickbooks.intuit.com/ca/. From there you can sign into your account and manage your payroll as normal. You're welcome to ask questions. I'll be a message away in case you have other questions.
