Once you have posted an EFT deposit to your checkbook, the situation may arise where you need to void that EFT deposit.  This can be done by selecting the ban icon inline next to the edit icon.  

You will be prompted with a confirmation to be sure you want to void this transaction.  Select “Yes” to complete the void.  

By completing the void, the system will create the reversing entry removing the funds out of your checkbook on the date of the void.

NOTE:  Previously reconciled checks cannot be void from the checkbook history screen.  To void previously reconciled items, see the article How to edit a reconciled item
