I'm here to assist you, taytumb.

When deleting a transaction, simply open or select the transaction and click on Delete on your keyboard. You can also press Command + D as a shortcut. Just a heads up, we're unable to undo once we successfully deleted it.

In addition, make sure that you haven't reconciled your account. It's because deleting a transaction can affect your beginning balance.

Please post again if you need more assistance. Have a great day!
