I've got your back to get rid of duplicate transactions on your banking feeds, @AngelaA13.

When doing a manual update, QuickBooks will download whatever your bank will share with us. That being said, you can only clear duplicate transactions by excluding them. 

At times, we roll out enhancements based on our customer's requests. That being said, I suggest sending a recommendation to our product developers to ensure you can clear all duplicate transaction in the register. They'll review this idea and might consider updating it in the future.

Here's how:

1. Go to the Gear located at the top.
2. Under Profile, click Feedback.
3. Enter your recommendation and select Submit.
