Thanks for dropping by the Community, @Deej4.

Deleting multiple transactions by batch is only available in QuickBooks Desktop Accountant 2017,  Enterprise and Enterprise Accountant 17.0, and later versions. Since you're using the Premier version, the only way to delete transactions is to manually do it one at a time.

Here's how:

1. Go to the Lists menu at the top to get to the Chart of Accounts. 
2. Select the account where the transactions are posted to open the register. 
3. Right-click on the transaction, then choose Delete. 

Just in case, I'll add this article for future reference: Batch delete or void transactions in QuickBooks Desktop Accountant Edition.

Please let me know if you have any other concerns or issues, and I'll get back to you right away. I'm always here to help. Enjoy the rest of the day!
