As has been posted in response to earlier threads related to the jobstep program task, ASCBXTCB contains the address of the jobstep program task when a job is active in an initiator or a started task's jobstep program has been attached.
And, similarly, TCBJSTCB of *your* TCB (PSATOLD) will locate this task unless that jobstep program task itself attached a jobstep task and you're running under that attached task or a subtask thereof. TCBBITCB is on in any task that is within the job step ("beneath initiator TCB").
