Hi there, toddschwartz.

For now, you still need to enter a physical location in the Mailing or Company Address in QBO. We appreciate and have taken note of all the feedback and suggestion about this. 

You can visit this site to get the latest updates and newly added features in QBO: https://quickbooks.intuit.com/blog/.

Let me just also re-share this article about changing company information in QBO for additional reference: Change Your Business Name, Contact Info, Or EIN In QuickBooks Online.

The Community is always here if you need anything else.
