Thanks for joining the Community, Thea Iris.

I've reviewed our ongoing/solved investigations and can confirm there's currently no records of subscribers reporting that some of their assigned classes aren't showing up in the Transaction Detail report.

Since your classes for income transactions aren't showing up, I'd recommend using the Verify Data feature to see if anything needs to be rebuilt.

Here's how:

1. Choose Window, then Close All.
2. In your top menu bar, go to File.
3. Click Utilities.
4. Select Verify Data.

After verification's complete, you'll see one of a few possible messages. I've listed each of them and their meanings:

• "QuickBooks detected no problems with your data," - No action is required.
• "Your data has lost integrity," - This indicates that there's data damage in your company file. You'll want to perform a rebuild to correct the problem.
• An error message could display. If so, there might be an article about it. Try searching Intuit's QuickBooks Desktop support site for specific instructions.

If your Verify/Rebuild Data utilities didn't solve the issue, you can get in touch with our Customer Care team so they can conduct further research:

1. In your top menu bar, go to Help, then QuickBooks Desktop Help.
2. Click Contact Us.
   
3. Enter a brief description of the issue in our Ask a question (or tell us what's wrong) field.
   
4. Hit Continue.
   
5. Select We’ll contact you for a callback or Message Us to start an instant messaging session.

They'll be able to pull up the account in a secure environment, conduct further research, and create an investigation ticket if necessary. Be sure to review their support hours so you'll know when agents are available.

I'll be here to help if there's any additional questions. Have a lovely day!
