I am a doctor in a government hospital and last year I got Rs.2,17,680 as salary for which TDS was deducted and Form 16 was issued accordingly. Apart from this I also earned cash of about Rs.63,750 for which I don't have any documentary proof and TDS was not deducted. But I paid an advance tax of Rs. 9000 before the due date. Now how should I file the return?
