Payroll Item List

I'll help set up the employee's negative paid time off as a deduction in your QuickBooks Desktop Payroll, @AbbyHCU.

As usual, you can set up the deduction in the Payroll Item List section. Let me guide you on how:

1. Go to the Lists menu and select Payroll Item List.
2. Press Ctrl + N on your keyboard, choose Custom set up, then Next.
3. Pick Deduction, then Next.
4. Enter the name of the deduction, and hit Next.
5. Complete the necessary information and click Finish. 

After that, assign the deduction to your employees. Complete the following procedures:

1. Go to the Employee menu and select Employee Center. 
2. Double-click the employee name and choose Payroll Info. 
3. Add the deduction item you previously created and click OK. 
4. You can then process your employee's pay as usual.

In addition, I would recommend contacting an accountant. They may have additional options that will meet your company's needs.
