Hi there, razorbackwater.
Opera Browser isn't one of the compatible or supported browsers for QuickBooks Online. It's recommended to use any of the following browsers to avoid unexpected errors:
- Google Chrome
- Mozilla Firefox. Note: To preview and print forms on Mac OS, you'll also need the Firefox PDF plugin.
- Microsoft Edge
- Safari 11 or newer (Mac only)
Please see the list of system and browser requirements here: System requirements for QuickBooks Online, Accountant, and Self-Employed.
Let me know if you need more help with QuickBooks.
