Welcome to the QuickBooks Community, april-versacg.
If you want to alter the name of the QuickBooks Checking account itself, this is currently unavailable. However, if you're referring to changing the business name associated with your QuickBooks Checking account, let me provide the steps to ensure you can perform the process.
I recommend signing in to your QuickBooks Payments account. You'll then have the option to modify your business information from there.
Here's how:
Choose Account, then Account Profile.
Go to Account Holder/Business Information and select Edit.
Change your business name and other needed info, then click Submit.
In case you need additional guidelines on how to organize your QuickBooks Checking account efficiently and how it works, you can read this article: Use your QuickBooks Checking account.
If you're referring to something else, don't hesitate to add a comment below, april-versacg. I'm always around to help. Have a great day!
