Hello there, David Matyas! While QuickBooks Desktop doesn't offer a direct feature to batch delete unreconciled transactions, you can manually delete or void them. I'm here to support you and guide you through each step of the process.
Before proceeding, please ensure you back up your QuickBooks Desktop company file. This step is crucial in case you need to recover your data if an issue arises. Once backed up, carefully review the account and any duplicate entries before deleting.
Here's how to delete:
- Go to the Lists menu and select Chart of Accounts.
- Open the Account Register and choose the account containing the duplicate entries you want to delete.
- From there, select each of the transactions you wish to delete.
- Make sure to check the box for each transaction, select the Main tab, then click the X icon or select Delete from the dropdown menu.
- Choose either Delete or Void, and confirm by clicking OK.

However, if you are using QuickBooks Desktop Accountant version, you can batch delete or void transactions, which allows you to remove multiple transactions at once. This feature is exclusively available in the Accountant edition.
