How do I undo doubled up bank transactions?

I can share some insights on how to resolve duplicate transactions in QuickBooks Online, @msdetmers.

When the bank transactions are imported and were successfully added in the register, this can't be undone manually. You'll need to remove or delete them one at a time.

Don't worry, I have a few options available for you to try in case you need to remove entries in the future.

If those entries to be undone are added transactions from the Banking page, you can undo and exclude them. To do that, follow the steps below:

1. Go to Banking menu, then tap the Categorized tab.
2. Find the transaction and select the Undo link under the action column.
3. Go to the For Review tab.
4. Mark the box next to each transaction you want to exclude.
5. Select Exclude from the pop-up at the top.
   

Excluded transactions are then moved to the Excluded tab, and won’t be added to QuickBooks or be downloaded again. To permanently delete duplicate entries, put a check mark on them, then hit Delete.

If it was already added in the register, you can manually delete them. The following link will guide you how to remove entries in QBO: Void or delete transactions in QuickBooks Online

Another option is finding a third-party deleter app to remove the data inside QuickBooks. Click this link to our site: QuickBooks Online Applications
