Advance tax - 44ad - fy 2015 - 2016

Hello,

I am filling Income tax return for FY 2015 - 2016 under 44AD (ITR4S). As I am filing late so there is interest caclulaion under u/s 234 A but u/s 234 B and u/s 234 C are not auto poplulated and blank. My question is am i supposed to pay advance tax and fill 234 B and C manually? becaue when i click at caculate tax these 2 fields are nullified. I have heard that advance tax is mandatory for 44AD for the FY 2016 - 2017 but not applied to previous financial year. Also I have other income sources (Bank interest) which I have filed under ITR4S form so is advance tax applicable on income other then business ? like bank interest.
