Add the ITC of inward supply under Revrse charge in your Next 3b.
In case of Exempted supply:
show the amount by deducting the amount equal to exempted supply wrongly shown with current month's exempted supply.
But if you dont have any exempted supply then cannot reverse the same . Just prepare reconciliation for the mistake done
