I left out one invoice by mistake in GSTR 3B of Nov 2018 due to which GST was less paid and turnover was shown less in 3B return. I am presently filing quaterly returns. How to adjust this mistake ? Shall I add this invoice in GSTR 3B of Dec 2018 or it has to be deposited while filing quaterly GSTR 1 return?
