Bank account keeps doubling up transactions

Hi orders18,

I can help you delete these duplicates. 

If the transactions are still showing in the For Review tab: 

1. In the left navigation tab, click on Banking.
2. In the For Review tab, select the duplicate transactions. 
3. Click on Batch actions and select Exclude Selected. 
4. In the Excluded tab, check the boxes for these duplicates.
5. Click on Batch actions and select Delete.

If these duplicates are already accepted/matched, here's how:

1. In the left navigation tab, click on Banking.
2. In the In QuickBooks tab, select the duplicate transactions. 
3. Click on Undo.
4. In the For Review tab, select the duplicate transactions. 
5. In the Excluded tab, check the boxes for these duplicates.
6. Click on Batch actions and click Delete.

For future reference, you can compare transactions of what you entered in QuickBooks. Please visit this article for your guide: Reconcile An Account in QuickBooks Online.

Let me know if you need anything else. I'll make sure to get back.
