I appreciate your effort in performing the steps above to resize columns, @Saralyn.

Let's do basic troubleshooting to identify the cause of the behavior. To start, I recommend accessing QuickBooks Online through a private browser. This is a special mode that doesn't leave browsing history. Here's how:

• Press Ctrl + Shift + N (Google Chrome).
• Ctrl + Shift + P (Firefox or Internet Explorer).
• Control + Option + P (Safari).

If the column separator icon, then let's go back to your regular browser and clear its cache. Cache can sometimes cause issues when trying to do certain tasks in the program. Also, you can try using a different supported browser. This way, you can check whether this has something to do with your browser.
