Gstb3

WHILE FILING GSTR-3B ...I COULDNT FILE THE INPUT TAX CREDIT(ITC RETURNS) AND  UNFORTUNATELY SUBMITTED THE GSTR-3B....SO AN HUGE AMOUNT OF TAX HAS BEEN ON MY LIABILITY SIDE WHICH I HAVE TO PAY.

CAN I MAKE ANY MODIFICATIONS ON THE SUBMITTED FORM..OR ANY OTHER WAY TO ENTER ITC RETURNS TO MY GST ACCOUNT?

WHAT MEASURES DOES I NEED TO OVERCOME THE TAX LIABILITY ?KINDLY CLARIFY
