GST-9(FY 2018-19)

Although the outward liability figures are auto populated in GSTR-9, you can always change it and show correct liability and pay the extra liability in DRC-03 

You can change all the figures in Table 4 of the GSTR-9. Calculate the liability manually as GSTR-9 dont calculate itself. Once Done, pay the liability via DRC-03 Challan
