This is a repeat query that was already answered earlier. For your ready reference, my reply is reproduced as under:
The TDS @ 10% implies that the company is treating you as a professional and making payments for your professional services and not as an employee. Your income will then be assessed under the head : " Profits & gains of business or profession". You may need to explore whether the presumptive tax will be applicable to you, as your turnover is Rs 15 Lakhs only. Even otherwise, you can claim reasonable expenditure actually incurred for the purpose of earning your income, such as salaries, rent, power, communication expenses etc.
The exemption u/s 80C is limited to Rs. 1 Lakh ( which is enhanced to Rs 1.5 Lakhs from the current financial year). Thus your claims towards Repayment of housing loan, PPF and LIC contribution will be restricted to Rs 1 Lakh only.
You will be eligible to claim interest on your housing loan under the head : "Income from House property". If the property is let out you need to offer rental income also.
The deduction towards mediclaim policy u/s 80D will be Rs 15K towards insurance premia for policies for self and family and another 15K for parents.
As regards your follow up question, you can make online payment of tax through income tax department web site. As a professional you can offer your income on receipt basis and if you have not received salary (?) for two months, you need not offer that income now and offer it as and when received.
