You are required to list all your debt on Schedules D, E and F. Not allowed to "pick and choose." However, you can on your own pay back whatever debt you'd like, including any listed debt to be discharged although this would not make much financial sense to do that. If you have only one creditor then it is permissible to file on that one creditor only, no limit on how many or how few creditors you may have.
