Capital gain tax on resedential property sale

Hi,

Please guide on Capital Gain Tax.

My Father purchased a property in 1968, After my father demise I sold the property on 3rd June, 2018 worth rupees 1.2 CR. The said amount I kept in Fixed Deposit for the period of 9 months. My two questions are :1. Please guide what is the time limit (period) to open Capital Gain Tax Account.

2. As I kept sold amount in Saving Bank Account and Fixed Deposit, Do I need to pay Tax for these 9 months. 

3. Please also suggest If now I open the Capital Gain Account, Do I need to deposit the interest of 9 months as well

Thanks
