In a  two trading firms, one firm sales are  1,90,00,000  and  the other is some 87,00,000,

In this,  we have filed the GSTR1   with correct  numbers and while filing of GSTR3B  for  the second firm, instead of   87,00,000  we have posted 1,90,00,000 and the 5% tax is also  been paid.

Pl  suggest me, how do i rectify it.
