Entered duplicate data from bank. I removed the duplicate items using the account register but they have reappeared. Audit history shows them deleted. What to do?

Thanks for reaching out to us, @userkevin.

It's my utmost priority to help you fully eliminate your duplicate bank transactions in QuickBooks Online.

You'll need to exclude the bank transactions from the For Review tab. This way, the transactions will then move from the For Review tab to the Excluded tab. From there, you can delete the transactions by selecting Batch actions, and clicking Delete.

Here's how to exclude the transactions:

1. Go to Banking menu on the left panel.
2. Choose Banking tab.
3. Check the box for beside the transactions you want to exclude.
4. Click the Batch actions drop-down and choose Exclude Selected.

After that, you can now delete them from the Excluded tab: 

For additional information about excluding and deleting bank transactions in QBO, feel free to scan through this link: Learn how to exclude a downloaded bank transaction.

However, if the problem continues, I'd suggest reaching out to our Customer Care Team. They have the tools that can help investigate the root cause of this behavior.

To do that:

1. Click on Help at the top menu bar.
2. Hit on the Contact Us button.
3. Enter a brief description of the issue in the What can we help you with? box.
4. Press on Let's talk.
5. Select on Get a callback.
6. Key in your contact details, then tap on Confirm my call.

I'm just a few clicks away if there's anything else you need. I'll ensure you're all set. Wishing you all the best in everything that you do.

When I go to the bank register (through Transactions/Banking)  I am given the choice of deleting an item in the right hand column.  Doesn't this achieve the same thing?  

It's another way to delete transactions, userkevin.

You can use either of the two to delete transactions. It's unusual for a transaction to show as deleted on the audit log but still exist on the account register.

I recommend contacting our QuickBooks Support to report this. They will be able to work remotely on your account or send a report to our product engineers. Just follow the steps given by my colleague to get in touch.

If you have other concerns, don't hesitate to leave a reply.
