Hello aleksandra-saleh,
Welcome to Community! Having additional transactions automatically categorized can impact your work. QuickBooks Online provides the option to categorize and match your transactions automatically, based on suggested categorization or associated rules. This option can be turned off, so you can categorize and match your transactions manually. I would be happy to show you how!
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 settings ⚙ above the Action column
4. Remove the checkmark beside Enable suggested categorization
That should do it!
If you experience the same result, please don't hesitate to contact us outside of Community. We would love the opportunity to work with you in real-time, and ensure you're able to accomplish your banking goals as soon as possible!
Feel free to reach out again, if you have other questions. We would be glad to assist!
