trouble with classes

You may have 2 options:

1. Purchase a 3rd party service to convert your data with class.

2. Start your data in QBO from scratch and use the trial version of QB Desktop to access your historical data for good.

I'd be happy to assist you here in the Community, @drciotola.  

One possible reason is that your transactions were classified by class one to entire transactions and not one to each row in transactions. That's why QuickBooks categorized the other side of your transactions by class and the other side as unclassified.

With this, we can manually categorize your transactions by class, or you can use a third-party service to convert your data with class, as suggested by 4Gal above.

Additionally, you can check out these helpful articles about migrating your data:

If you need to run a report by class, please refer to this article for guidance: Run reports by class in QuickBooks Online.

Let me know if you have further queries about your transactions by class or QuickBooks. Keep safe. 

Thank you @RogelioL 

I would like to take you up on your offer of showing me how to do it manually.  Thats because although I am going to check into those 3rd party vendors, I don't know that we have access to the QB desktop file anymore from the [previous accounting firm.  I believe access to that has expired.  So I would really appreciate your help.

hi @RogelioL 

Would really appreciate your help in showing me how to do this manually.  We may not have access to the file from the previous firm anymore to give to a 3rd party vendor.  Sorry if this posts twice computer acting weird.

Let me assist you on how to categorize the unclassified class, @drciotola.

You can choose to assign a single class to a complete invoice, receipt, or any other customer transaction. These will save you time don't need to track each product you sell by class. If you wish to track your customer transactions, follow the steps outlined in the "Change how you tag a class in customer transactions" section.

Here's how: 

1. Select + New.
2. Select the type of transaction you want to record.
3. Add the details of the transaction.
4. Assign a class.
5. Save your transaction.

• To assign a class to each item (or row), add the class in the Class column for each transaction row.

Moreover, I'd be sharing these articles that can help you manage your account:

I'll be here if you still have questions about your class list. Have a great day.
