Canceling the query does not help with our need here. We were attempting to change the author of the service and the query schedules. Through Adobe support we learned there is no way to do this in AEP, which is quite inconvenient--all of the work had to be redone with another user account. If anyone sees this in the future, it is very important to log who creates any query schedules or DSW services as they will all break if that user is removed from the system (i.e. when the employee or vendor leaves). It seems a huge miss that DSW isn't capable of creating the services / scheduled queries agnostic of the user, but we have confirmed it is not a feature and Adobe has no plans to improve it at this time.
