How to Change A ROUTING NUMBER for a bank account?

Welcome back to the QuickBooks Community, ljonesver.

I've got steps you'll need to ensure you can change a routing number for your bank account in QuickBooks Online.

I recommend going to the Payroll Settings section and you'll be able to modify any bank information from there. 

Here's how:

1. Choose Payroll Settings from the Gear icon.
2. From Bank Accounts, click the pencil icon ✎.
3. Choose Update.
4. Select Add new bank account.
5. Search your bank name. You may be asked to enter your online banking user ID and password. Otherwise, choose Enter bank info manually. Enter your routing and account number, then click Save.
6. Choose Accept and Submit.

In case you need to see the different payroll account types you can use to track your payroll transactions, you can read this article: Change your accounting preferences in QuickBooks Online Payroll.
