How to deposit tax on credit note issued by supplier

Hello everyone,

Our supplier issues us credit note (cash discount) on the invoice, and also puts 12% gst on it. This 12% GST claimed from him , is to be deposited by us.

Please advise which column is to be used for this purpose in GST3B. Currently we were using "ITC reversed" for this purpose. but we are informed, its not correct, as ITC REVERSED coloumn is for 180 payment delay .

any help will be appreciate in this regard,

thanks
