Glad to have you post in the Community. QuickBooks makes it easy to add vacation hours to your payroll.
When you're running payroll, you can enter the vacation hours your employee took. Although, the hours she took are over what is banked, you should be able to edit an employee's vacation policy by following the steps below:
If you are updating an Employee's vacation, go to the Employee tab.
Select Edit next to the employee's name.
Go to the Employment tab.
Enter employee vacation information.
Select Save.
Let me know if this helps. I'll be here if you need me.
