Hi there, Jamie.
The error you received when trying to delete the duplicate tax payment in the register indicates a technical glitch, such as browser cache issues. Sometimes cached data can interfere with QuickBooks Online. Clearing this data can help resolve errors.
Now, let’s try some troubleshooting steps to see if this issue is related to your browser. Start by clearing your browser’s cache to refresh the system and remove any outdated files that might be causing the problem. Additionally, make sure you're using a supported browser to ensure QuickBooks runs smoothly.
If the problem persists, I recommend contacting our Live Support Team. They can securely access your account and offer more personalized assistance.
