My client made an export of goods with payment of IGST of Rs.66600/-in May 2018 and filed GSTR-3B as shown in Table 3.1(a). further filed GSTR -1 for quarter ended on 30/06/2018. My client had received shipping bill in the month of August 2018. I filed GSTR-1 without showing details of shipping bill details. Now my client want IGST refund. What should I do now?

Further invoice details not shared with ICEGATE while track status of it.
