Gst details in ITR 3

GST input and output is to be shown in the ITR 3 p& l or balance is to be shown in balance sheet?

ex: GST input on purchases Rs.10,000 and out put on sales Rs.15,000/- GST paid Rs.2,000/- Liable to pay as on 31-03-2019 Rs.3,000/- all these are to be shown in the ITR 3 or only liability of Rs.3,000/- shown in the Balance sheet? pls clarify.
