Hi there, accounting366.
There are times that the browser keeps outdated Internet files that may cause websites, like QuickBooks Online, to receive unusual behavior.
I suggest logging into your QBO account using a private browser. This way, you're able to verify if too much data saved in your browser is causing why you received an error when setting up the system.
Use these keyboard shortcuts based on the browser you're using.
If it works in incognito, I recommend clearing the cache of your regular browser. This way, it can resolve many different issues and is a good place to start whenever you see unexpected behavior in the product.
If the steps above didn't work, use another supported browser as alternatives.
Please refer to this link to look for some information on how to organize your QuickBooks account and click each topic to view them: Help articles.
May I ask what are you trying to set up? I'd appreciate any further details so I can provide an accurate solution.
Please know that you're always welcome to post if you have any other concerns. I'm always here to help.
