Rule 45(3) of the CGST Rules provides that the principal is required to furnish the details of challans in respect of goods send to a job worker or received from a job worker or sent from one job worker or received from a job worker or sent from one job worker to another job worker during a quarter in FORM GST ITC – 04
So, you required to show that details in ITC 04, not in GSTR 3b or 1.
