Thanks for reaching out to the QuickBooks Community, @PTJ.

I'm here to help resolve the issue when filtering Balance Sheet Report by Class in QuickBooks Online (QBO). 

I've replicated this on my QuickBooks sample file, and it seems like my bank deposit shows when filtering the Balance Sheet report by Class. Let's perform troubleshooting steps, which is to switch to a different browser. This is a good way to check if it's caused by the browser. Let's log into QBO using a private browser. 

Here are the keyboard shortcuts to open a private browser: 

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

If it works fine, I suggest clearing your browser's cache to start fresh. The next time you log in to QuickBooks Online, your browser will download fresh copies of everything you see on each page. Any cache-related issues should be cleared up. 

For additional reference, you can check this article on how to customize reports. 

Please let me know how it goes by clicking the Reply button below. I'll be around to help if you have additional questions about the QBO reports. Have a good one.
