I'd like to start with opening a Private Window or an Incognito Window in your web browser. This will open your account in a clean slate and loads fresh data. Here's how:
Mozilla Firefox / Internet Explorer: Press CTRL + Shift + P
Safari: Press Command + Shift + N
Google Chrome: Press CTRL + Shift + N
Once you're in the Private / Incognito Window, sign in to your QuickBooks Online account.
