 Sir in reply to point iv) my tds deducted in fy17-18  so as per your explanation i must show that amount being deducted in 2017 but as u can see in the attached pdf previous year tds in utility shows only upto 2016  . And the next option in utility is TDS of current financial year .my question is how will i know the tds of the ongoing financial year beforehand cause i earn commission money which varies from month to month.

Here, current financial year (for TDS) is 2017-18, and your TDS amount 1595 for FY 2017-18, is rightly filled.

No need to fill anything in brough forward, as it is nil, in your case.
