Good evening, jagwani.
Thanks for reaching out to us here. I'd be happy to help!
QuickBooks Online provides the option to view the banks across the top of the screen. Below the "Update" in the far right corner, you should be able to see a small arrow pointing down, simply click on the arrow and the list of banks should appear back at the top of the page. I hope this helps!
Please feel free to let me know if you were able to get this figured out.
