Thanks for reaching out to the QuickBooks Community, a-mitchell.
Allow me to step in and help guide you on how to change the location label to division in QuickBooks Online (QBO).
To do this, please follow the steps below:
Once done, you can now open your location list to show the Division where you can categorize the transactions by different parts of your company.
For additional reference, you can check this article and scroll-down to Location List: Change company name, address, email address, EIN, and privacy settings.
That should do it! Feel me in if you have additional questions about the location feature. I'm always here to help you out.
