I am doing Carting business and 5% gst rate applicable on my business.

I was sales to client (B2B) rs. 1,000/- and gst rs.50/- on sales. and also provide transportation service of rs. 300/- to client on RCM basis. Transportation gst paid by client.

Question : 1) How to show transportation income rs 300/- in income tax return.
2) what treatment of transportation service in gst (GSTR 3B and GSTR 1).
