Hi there,
Welcome to the Community. Glad to learn you're using QuickBooks Payroll to help streamline your payroll. I'll be happy to share more info so you're on the right track.
I recommend deleting the cheque and re-running the payroll using the desired pay method. It's important to note deleting a paycheque will completely remove it from your account. You can only delete a paycheque if it's the most recent cheque for an employee. When you delete a paycheque, our system will automatically recalculate your tax liabilities. Here's a helpful article that provides more info on how to: Delete a paycheque in QuickBooks Online.
Let me know if this info helps. I'll be here to help if you have other questions.
