ITC Taken wrong head

Partha Sarathy   20 January 2021

Sir,

     I have wrongly ITC taken in CGST & SGST Instead of IGST. and the difference showing in Annual Return (8A Vs 3B)

Examble:

Supplier filed in GSTR1 at IGST Column. Rs3.2 lakh. but Asper 3B   i have taken CGST & SGST .

Kindly guide me how rectify this mistake. Our auditor suggested remit the amount of Rs.3.2 lakh in IGST Account.
