I pay my federal 941 quarterly. So how do I change the payment to reflect the quarterly amount instead of the monthly amount?

Thank you for joining us here in the Community, davidfox.

I'd be glad to help you out with your concern. However, I have to ask for more details to get me on the same page. 

May I know your tax deposit schedule? Did you process the payment via EFTPS or through QuickBooks Online (QBO) Payroll? Which area of the Payroll Tax Center do you wish to reflect the payment?

You can go over this reference to learn more about the deposit and filing schedule change process: Change your payroll tax payment or filing schedule.

In addition, the following guide contains topics to easily get around payroll tasks: Get started with QuickBooks Online Payroll.

You can always reach out to us if you have other payroll concerns. I'd be glad to get back here and offer my help again.
