Submit response to 143(1)(a) communication from cpc

Hi ,

I have received communication from CPC to submit response to 143(1)(a) which stats "There is inconsistency between Other Source income in return and Form 26AS". then  i checked my form26AS where under section 194A interest are received in my account either from RD or saving acount interest which comes 11398 rs from Rd acoount and  7703 rs from Saving Account interest  but in CPC communication they mentioned only 11398 rs.

Now as far as i know i should file reviesed return and need to add 11398 rs as other source of income but they already deduct TDS of 1140 rs for this interest amount. Should i add saving account interest i.e. 7703 as well to my other income (11398+7703 = 19101 ) . 

1. Which income i should mention as other source of income 11398 or 19101 because commuciation mentioned only 11398 ?
2. How would i claim TDS which is already deducted ?
3. Can i claim 10000 interest free exemption but how 

Any help appericiated.
