Can I place a stop payment on a check I have written or an electronic (ACH) withdrawal that was previously authorized on my account?

Log into Digital Banking. To place a stop payment on a check I wrote: Select the MORE widget and then select the ADDITIONAL SERVICES widget. Select the Stop Payment option from the menu. Select the "New Stop Pay Request" button. Complete the information requested and press the  Submit Request button.
