Hi andersontowing-a,
Welcome and thank you for getting help with removing the garnishment deduction on your employee's future payroll. I'll help out.
To do this, you'll want to go to the employee's profile, edit his Deductions and Contributions section, and delete the Child support garnishment. This step will not delete the previous records if that item was already used before. When you run a Payroll Summary report after deletion, nothing will be changed in that report.
Feel free to go back to this thread if you have other questions in mind. Take care and have a good one!
