On Quickbooks basics, how do I remove sub class on. I don't need all these classes. I to simplified.

I'd be glad to help you remove the sub-class in QuickBooks Online (QBO), motox594cr. 

We can deactivate the sub-class to remove it from your class list. Please note that deactivating a sub-class doesn't permanently delete from your account.

Here's how:

1. Choose the Gear icon and click All List under List.
2. Select Classes.
3. Click the class to delete (make it inactive).
4. Go to the Report drop-down arrow under the Action column.
5. Click Make inactive.
6. Select Yes to confirm.

To learn how to add, delete, or restore a class in QuickBooks Online, I suggest browsing this article: Create and Manage Classes.

Additionally, I've added an article that'll help organize your customer and vendor transactions by class. This ensures your data is accurate: Track your Transactions by Class.

Get in touch with us if you need further assistance in managing your classes. I'm always here to help.
