Yes It is right,

You can claim PRINCIPAL repayment u/s 80C and INTEREST portion can be claimed under the head Income from House Property,This will be taken as loss from House property and will be set off against other income...

Dear Naveen firstly you have to activate excel sheet if you don't then cells effect can not activate. You can get deduction after filing the amount of interest above said coloumns. After the write you have to VALIDATE the sheet if sheet is ok then you can see the effect on the page of PARTB-TI-TTI. 

Thanks & regards
