Thanks for checking in with us, kelseydallas28.
I'd be happy to share some information about setting up bill payment for multiple child support in QuickBooks Online.
You can create an expense transaction for each child support.to pay your employee's garnishment and use the liability account that was set up for garnishment.
You may find this article helpful: Set up a garnishment.
If you're referring to something else, please let me know. I'll be around to help.
