Thanks for joining the thread, @dickens14.

Let's run some troubleshooting steps to address your concern. A minor data damage in your company file might be the cause of this behavior. This can be the reason why you're unable to add a line item even after creating a new account. 

To start, let's update QuickBooks Desktop to its latest release. This will keep your software up-to-date so you always have the latest features and fixes.

If you're still getting the same result, I suggest running the Verify and Rebuild tools to isolate this issue. This tool scans your company file for errors and fixes them right away. Let me show you how:

To Verify:

1. Go to the Window menu and select Close All.
2. Then, go to the File menu.
3. Select Utilities.
4. Click Verify Data.

To Rebuild:

1. Go to the File menu.
2. Select Utilities.
3. Click Rebuild Data.

Moreover, you have the option to personalize your report to focus on the data that matters to your business. To be guided through the process, you can utilize this link for your reference: Customize reports in QuickBooks Desktop.

Let me know if you have any other concerns or questions about managing your reports or with your account. I’ll be around ready to lend a helping hand. Have a good one.
