Sir
In the month of March 3018 i have filed GSTR 1 taking all the sales. But while filing GSTR 3B i have wrongly filed without taking sales and purchase values. The input amount is roughly 4lakhs. this i have not filed in Gate 3B. Now while filing GSTR 9 can i take this input amount or i have to pay the entire amount of input. please clarify in detail.
