It appears that you have inducted into QRMP by default. As a QRMP taxpayer, you are to file IFF for Jan & Feb and file GSTR 3B for Mar. You have the option to pay your taxes for 1st two months either by paying 35% of taxes paid in last quarter or by paying your self assessed tax for each month through PMT 06.
