Set off of income tax paid in previous financial years

Hello,

I have an issue while filing this years IT return for FY 14-15. 

1. Our company had a Super Annuation Fund (SAF) to which company used to contribute a certain amount based on Basic salry every year. 
2. In 2014-15 company gave us an option to withdraw this amount which I accepted. Copmany paid me a lumpsum amount after deducting TDS.
3. I come in the 30% income tax bracket.
4. Since Super Annuation amount was above Rs 1 Lacfrom FY 2009-10 onwards, the additional amount abobe Rs 1 Lac was shown as perk and Taxed already in last 5 FY
5. So in the final settlement, company deducted the cumulative perk amount in last 5 FY from the groos accumulated amount in Super Annuation Fund before calculating the TDS
6. My problem is how do I account for this amount (cumulative value of perk which is already taxed in last FY) while filing current AY tax return?

Please advise.
