Hi there, lunarindustrial.

The reason the item is not showing in the Other Payroll Items section because you created the paycheck before setting it up.

To sort this issue, I suggest reverting the paycheck by following these steps:

Here's how:

1. Click Employees menu.

2. Choose Payroll Center.

3. Select Pay Employees tab and click the Start Unscheduled Payroll button.

4. You'll be routed in the Enter Payroll Information page. Then, right-click the name of the employee and select Revert Paycheck.

I attached screenshot below for visual reference.

For additional information on reverting a paycheck and how to save paychecks and return later to finish creating payroll without losing your data, please check this article: How to save or revert pending paychecks.
