Sir,

I had Already filed Gstr9 without entering data in Column 6B. 

Can not  do anything now if you are having data  of  Inputs , capital Goods , Input  services in 6(B) of  GSTR9  , You  can  contact  to  your  nearest  Jurisdiction  office  , Department  of GST  and  inform   . you can not revise  GSTR9 ones filed .
