  You may find that you can go to this url and find the field you are looking for
  /civicrm/admin/custom/group/field/update?action=update&reset=1&id=
  
  Or, to reverse engineer this, go to any existing custom field and mouse over the view/edit links and you should see the field ID along with the field group ID - i just dropped out the field group id to make the url look a little less intimidating.
