Adsense income can be claimed under section 44AD or 44ADA?

I have a website and my earnings are from Google Adsense.

I display ads on my website, these ads are provided by Google. I earn from these ads.

During the year I have received around 20 lakhs from Google Adsense ad network.

My question are:

1. Adsense income can be claimed under section 44AD of Income Tax Act?
2. Adsense income can be claimed under section 44ADA Income Tax Act?

If Adsense cannot be claimed under above sections, what expense I can claim and how much income tax I should pay?
