Itr filling - saving account interest/exemption

I am filling Revised ITR for Assesment Year 2015. Earlier I forgot to declare saving account interest in IOS.

Now I mentioned the interest amount which I found in Form 26 A, in of IOS section. Do I need to mention anything in 80TTA or not ?

For Ex: I earned interest of 12k as mentioned in Form 26A. Tax on this amount will be 10% i.e. 1200. Seeking this info I mentioned 12000 in IOS. Do I have to mention any deduction/exemptions anywhere else as well ? In which section is that 10,000 interest exemption will be mentioned.

Please help, this is my Revised ITR, dont want to make mistake again :( PFA screen shots as well.

Thanks & Regards
