I've got some steps for you to delete your payroll items, Ap.
As of the moment, the option to delete payroll deductions directly is unavailable. However, you can still remove payroll items by accessing a specific employee's profile and deleting it from there.
Here's how:
Go to the Payroll menu located at the left navigation panel and click the Employees option.
Choose an employee.
Scroll down until you see the Deductions & contributions section.
Click the Edit.
Choose a deduction you'd want to delete and press the Trash Bin icon.
You'll be prompted with a message. You can select Delete if you're certain.
Once you're done deleting the items you'd like to remove, click Done.
