Welcome to the Community forum, Rey.
To ensure that I am providing the right solution, could you please specify which section of QuickBooks Online (QBO) you are trying to add a new category to? Is it in the chart of accounts or in the products and services? A screenshot would help.
In the mean time, let's perform basic troubleshooting steps to determine what's preventing you from adding and saving the new category.
If you're using mobile, here's how:
- Close and restart the app.
- Delete app data .
- Switch off and restart your device.
- Uninstall and reinstall the application.
If you're using a web browser, here's how:
- Launch your browser again.
- Open your QBO company using a private window.
- Empty the cache on your browser.
- Add Intuit as a trusted site.
Moreover, read this article for future reference on how to organize all of your reports in QBO: Run reports in QuickBooks Online.
We'll be keeping an eye on your reply for further details about the category or if you have other concerns with any QBO products. We're always here to help. Have a good one.
