Hello Shashi,
This following link is showing the tapping points quite clearly,

If you use several fingers as you tap, you cover a larger area especially under the arm.
And yes, you are doing it right, with your phrasing, remember words are just there to connect with the block. so tune in...and don't hesitate to follow up what may come up...
Happy tapping,
Fabienne
