I have holding in my demat bt i am not able to see in zt software,and also tell me how can i sell the stocks which i bought

In Zerodha Trader go to 

view -> order and trade report -> view holdings

you can see your holdings,

You can sell by selecting script press f2 and select order type CNC

i did this to see in order book and trade history by also its not showing there ,every time i go to back office to see my holdings.
and selecting script press f2 is for selling the stocks which i bought previously correct?
