Hello there, @JonLMHCPA.
At this time, the option to batch edit the payees after the reconciliation is unavailable in QuickBooks Online.
As a workaround, you can manually edit it on the Bank register section. Let me guide you how.
- Go to the Gear icon.
- Select Chart of Accounts.
- Locate the transaction, then click View register.
- Select the drop-down list on the Payee/Account column.
- Once done, hit Save.
I'll add these articles as your references on how to find, edit and update account registers/banking transactions in QuickBooks Online:
Don't hesitate to comment below if you have further concerns. I'd be glad to assist you as soon as I can. Take care.
