Export Sales with IGST Payment made by one of our new client in the month of Mar 2019, but which has not disclosed in GSTR1 and GSTR3B. I need two clarification regarding the above :
1. Where to shown the missing sales in Annual Return GSTR9?
2. If I will declare the export sales in GSTR3B and GSTR 1 in the month of April 2019, then can I receive the refund of IGST amount?
