I'd like to welcome you to the Community, michelet. I'd be happy to assist with your questions about managing vacation accruals in QuickBooks Desktop.

There's an option in the program to exclude vacation or sick hours in PTO accrual. This allows the system to only calculate the actual worked hours and remove the vacation time from the accrual.

Here's what you need to do: 

1. Go to the Edit menu and select Preferences.
2. Proceed to the Payroll and Employees tab, then go to Company Preferences.
3. Click Sick and Vacation.
4. Check the box for Sick and vacation hours paid under the Sick and Vacation Accrual section.
5. Click OK.

By excluding vacation or sick hours from the PTO accrual calculation, QuickBooks Desktop will only use the actual worked hours when calculating the accrual amount. This ensures accurate tracking and management of your employees' vacation time.
