Thanks for joining this thread, Maisy1.

I want to make sure you're able to view the subaccounts in your QuickBooks Online account.

Were you able to complete the troubleshooting steps listed above by clearing the browser cache? If so and the problem is persisting, I recommend reaching out to a member of the QuickBooks Online Support Team. Agents have specialized tools, such as the ability to share you screen, and take a closer look at the issue. Here's how to get in touch with the team:

1. Click the Help button in the top right corner.
2. Select Contact Us.
3. Enter Support in the field and choose Let's talk.
4. From here you can select to receive a callback at a time that's convenient for you, or begin a live chat session with an agent.

The following article provides these steps if you ever need them again in the future: QuickBooks Online Support

Please don't hesitate to reach back out here if you need a hand with your Chart of Accounts or anything else. Take care!
