Thanks for getting back to us, Virgie.

In QuickBooks, payroll deductions, like Child Support, are automatically calculated on the paychecks.

QuickBooks doesn't automatically send payments to the Child Support division. You need to write a check and manually send it to them.

In addition to this, you only need to write one check for the payment. No need to create another check for the employee.

You can refer to this article to learn how to make the garnishment payment: Set up and pay scheduled or custom (unscheduled) liabilities. It provides instructions to keep track of your payroll liabilities. 

Get back to me if you need more information about creating a check for the garnishment. I'm always right here to help you.
