When I try to correct my bank transactions and save I get the message: !You didn't select a class. Seletct a classs or add this transaction again." How do I correct this?

I've come to guide you as to how you can deselect the choice to insert a class on every transaction in QuickBooks Online (QBO), @docjay. This way, you're able to manage your transactions accordingly.

When you turn on the class tracking feature, you're able to disable the option to insert a class on every transaction. To do this, you'll have to visit the Account and Setting page and manage your Categories. Here's how:

1. Go to the Gear icon.
2. Select Account and settings.
3. Choose the Advanced menu.
4. Go to the Categories section.
5. Deselect the Warn me when a transaction isn’t assigned a class option in the Track classes section.
6. Click Save. 

Also, to further guide you in assigning classes to transactions and matching your bank feeds to the existing entries in QBO, I'd recommend checking out these articles:

• Track your transactions by class
• Categorize online bank transactions in QuickBooks Online

Let me know in the comments if you have other class tracking concerns and questions about managing transactions in QBO. I'm always around to help. Take care, and I wish you continued success, @docjay.
