Good day, ndamo.

Currently, we're unable to turn off the auto-match feature in QuickBooks Desktop. When QuickBooks tries to automatically match downloaded transactions to any entries, you can review the matches before adding them to the register. 

Additionally, the software makes a match if the bank feeds and the transactions that you've manually entered in the register have the same information.

To ensure the matches are correct, I recommend creating banking rules. For more details, I suggest checking this article's Optional - Create rules to categorize transactions section: Add and Match Bank Feed Transactions.

I've also included an article that'll help you ensure your accounts matches your bank statements. This helps you ensure your books are accurate: Reconcile Workflow.
