Share his contact here? My CA also files returns, P&L, Balance Sheet - he charges me 12k. FYI - I am relatively senior and my salary has been 35 - 50 lpa for the last 3 years

Don't waste your time Googling. It makes a lot more sense to hire a CA. For the first 4-5 years it isn't mandatory, but as soon as you hit 50 lakhs you'll be be audited and you might as well have an equation with someone you trust by then. The cost of CA in your early days will be less than 10K per year. They'll file your return and if you find a sufficiently aggressive one, you'll get a nice fat refund.

In terms of the law, as a lawyer (a profession for tax purposes), till you earn 50LPA, you can claim half your income as an expense, pretty much no questions asked. So at 16 LPA, you pay tax on 8 (minus standard deductions), which is likely less than the 1.6 that is cut in TDS (hence the refund).
