Thank you for giving those steps a try, TMC1900.
Since the issue with the tax is persisting I recommend reaching out to a member of the QuickBooks Online Support Team. Agents have specialized tools, like the ability to share your screen, to take a more in depth look to determine what's causing this to happen. Here's how to get in touch with the team:
1. Click the Help (?) button.
2. Select either tab to get started:
- Assistant: Get quick, personalized answers. Select a suggested option, or type a question or topic you need help with. If you decide you need further help, you can still Talk to a human.
- Search: Search the QuickBooks Online knowledge base directly, or select Contact Us and choose a way to connect with us:
a. Start a chat with a support expert.
b. Get a callback from the next available expert.
