@Anjali72
I see you created one listing, which is new and probably no bookings received yet ?
Please note your first 3 bookings have 20% discount (promotion), but that offer is also on long term stays (which you offer too !)
Regarding payout:
You need to setup a payout method in your account.
It is explained in this article:
Add a payout method

After a guest checks-in, the payout will be released on the next day, using your payout method.
All payouts ("earnings") will be listed in your "transaction history", read more:

Hope this helps
