Hello there, @dwogensen.
Thanks for choosing QuickBooks Online as your accounting software. I can help you know which account the money will go for the payment of the Garnishment.
After setting up the Garnishment on your employee's profile, you can go to your Payroll Preferences to verify the account associated.
For additional insights, you can check this article: Payroll accounting preferences.
Let me know if there's anything else you need about payroll items. I'm still here to offer more help. Just leave a comment below. Have a good one.
