You can simply go to your Payroll menu and then edit your employee's existing deduction from there. Here are the steps to do that:

1. Log in to your QuickBooks Online account.
2. Go to the Payroll menu, then click Employees.
3. Select the employee’s name.
4. Click the Pencil icon beside Pay.

6. Select the Pencil icon next to the deduction you want to edit.
7. Make any necessary changes.
8. Press Save, then Done.

Concerning the amount he paid towards the balance due, you can run the Payroll Deductions/Contributions report. This report shows employees' total deductions and the company's contributions.

Here’s how:

1. Select the Reports menu.
2. Enter/select Payroll Deductions/Contributions.
   
3. Filter the date and the type of deduction you want to track.
4. Press Run Report.
