Can't drop audio into timeline

Newbie here. I was moving along well until I tried to drop an audio track. Track (.wav)is already in media
I noticed my DR does not have the toolbar with the position lock, link symbol and magnet.
Also, on the bottom right of my screen, there is no slot for audio.
There are 2 tracks each with a V and an A, but selecting them seems to do nothing.
I'm using the free version. Maybe that's the problem.
Any help would be great.
