in 17-18 FY we forget to upload one sale bill for RS 1000/- +IGST RS 180/-.total invoice value is RS 1180/-
we upload this invoice in September 18 Gstr 1 and make payment through GSTR 3b.
in September we paid for rs 180/- + September 18 IGST amount RS 120/- together. Challan amount was RS 300/-.
Now question is when we fill GSTR 9 which column we put RS 180/- as IGST we paid in SEPTEMBER 2018
2nd question is in which column we put sales bill amount for RS 1000/- in GSTR9
