Csi file

Sir,

My doubt is regarding the selection of dates in csi file. My firm had paid for a short deduction for the tds in the 4th quarter for the financial year 2014-15. Now i have to file its correction return. So when i select the dates in csi file, which dates i should choose. ie from 01.01.15 to 31.03.15? or from 01.01.15 to 20.05.15? where on 20.05.15 my firm made payment for the short deduction. Pls reply in this regard
