How to save the withholdings?

Thanks for reaching out to the Community, @cherylc1.I'd be happy to help you save the withholdings in QuickBooks Online.

To make sure I'm on the same page, are you trying to set up withholding or garnishment for one of your employees? This article will help you get started: Set up and assign garnishments. Additionally, are you receiving any type of error message when trying to save? 

You can let me know by leaving a Reply below. In the meantime, this Community article provides even more information on how to set up payroll. I'll keep an eye out for your response. Talk to you soon!
