Has anyone had a problem putting in their account number because of a formatting issue? My required format is correct and I am being told that it is not.

Thanks for dropping by the Community, @aransashabitat.

We can perform some troubleshooting steps to fix this. There are times that the browser is full of frequently accessed pages, thus causing some unusual responses. Let's log in to your account using a private browser. This mode will not save any history making it a great place to identify issues in the browser. 

Access your QBO account in a private/incognito browser. You may use these shortcut keys that I've listed below:

• Google Chrome: press Ctrl + Shift + N  
• Mozilla Firefox: press Ctrl + Shift + P
• Safari: press Command + Shift + N

Then, put your account number. If it works, go back to your regular browser and clear the cache to delete stored site data and improve the system performance. Also, you can use other supported browsers. It could be that the one you're currently working on has a temporary problem with QuickBooks. 

Lastly, I've also included a couple of references below for ideas to help organize your chart of accounts:

• Create subaccounts in your chart of accounts in QuickBooks Online
• Delete an account on your chart of accounts in QuickBooks Online

Feel at ease to let me know how it goes. I'll be around to help you. Stay safe and have a pleasant day.
