No way to change mailing address in Intuit account "Preferences" pane

I appreciate you bringing this matter to our attention, @donutfactory.

Before anything, I'd like to know what product you currently use so I can provide accurate steps. 

Moreover, there's no option to modify the mailing address under Preferences in managing an Intuit Account. However, you can only change your email address and phone number. 

That said, I recommend contacting our Customer Care Support Team, who can investigate this further and provide you with more information. Here's how you can reach them:

1. Sign in to your QuickBooks Online company.
2. Go to Help (?).
3. Select Contact Us.
4. Enter your concern, then select Let's Talk.
5. Choose a way to connect with us:

• Start a chat with a support expert.
• Get a callback from the next available expert.

Moreover, you can browse this article to learn more about your subscription and update your billing information: Manage QuickBooks Online Subscription.

You're always welcome to go back to this thread if you have additional questions or concerns about updating your personal information or any other processes within the program. Have a good one.
