Welcome to the Community, @usertiffany-jape.
To check if the browser's cache and cookies are causing this odd behavior, try signing into your QuickBooks Online (QBO) using a private browser (incognito).
Once signed in, create an expense again to double-check. If it's successful, return to your default browser and perform a clear cache to refresh the system. However, if the issue persists, try using other supported browsers.
For more information about managing expenses in QBO, consider checking out this article: Enter, edit, or delete expenses in QuickBooks Online.
Please leave a comment below if you have any other issues or concerns. I'll be more than willing to help. Take care and have a good one!

They have tools such as screen-sharing (remote access) that can pull up your account in a secure environment and check the cause of this odd behavior. They can also perform other troubleshooting steps to fix this for you.
