Hi cara12,
There are a couple of areas to review, when QuickBooks updates your transaction to a specific category or payee. I would be happy to provide some insight here!
QuickBooks Online provides the option to set up bank rules, so you can categorize and match your transactions effortlessly. Each bank rule allows you to select the option to 'Automatically confirm transactions this rule applies to'. However, QuickBooks also provides additional options within your bank feed, that allow you to set your preferences accordingly. In your situation I recommend disabling 'Enable suggested categorization'. Here's how;
1. Open Transactions, then Bank transactions from the left menu
2. Select the tile for the account
3. Click on the small Preferences ⚙ above the Action column
4. Remove the checkmark beside Enable suggested categorization
That should do it!
