Let me share additional information to help you sort this out, @rav1.
You can delete and recreate the paycheck in QuickBooks. I can guide you in doing so.
Let's first view your payroll checklist as suggested by my colleague, @MadelynC. From here, let's open each paycheck that an incorrect amount. Here's how:
Go to the Payroll menu.
Choose the Employees tab.
Click the Paycheck List link below the Run Payroll button.
Set the date ranger to the 4th Quarter, then click the Run Report button.
Locate the paycheck that an incorrect amount.
From the Net Pay column, click the amount of the paycheck.
At the bottom menu, click Delete or Void.
Put a Check Mark in the I understand that this action cannot be undone box.
Click Delete Paycheck.
Once completed, you can recreate the paycheck. You can refer to this article for more detailed steps: How to Run Payroll.
Also, you can run and customize the Payroll Summary by Employee report. This way, you can view a comprehensive report of wages, deductions, and tax info, totaled by employee or period
