I am trying to turn off the suggested categories for bank transactions. For my checks it is putting all of them in the wrong category under the wrong vendor?

Hello there. Let's navigate together to turn off this feature to enable transaction categorization.

 To begin with, we need to ensure that the Enable suggested categorization is turned off. 

Here's how:

1. On the left panel, go to Transactions, then select Bank Transactions.
2. Click the small Gear icon beside the print icon.
3. Once done, locate the Enable suggested categorization, then uncheck the check box.

After this, the transactions will not change whenever you modify it to the correct Category and Vendor. However, if you still can't change it, we can perform basic troubleshooting by using a private browser. Private browsers will not save data, unlike regular browsers.

These are the keyboard shortcuts:

• Mozilla Firefox: CTRL + Shift + P
• Microsoft Edge: CTRL + Shift + N
• Google Chrome: CTRL + Shift + N
• Safari: Command + Shift + N

If it works fine from there, you'll want to clear your regular browser's cache. In addition, you'll want to check this article as a reference to learn how to reconcile your accounts so they always match your bank and credit card statements: Reconcile an account in QuickBooks Online.
