Income tax - communication u/s 143(1) (a)

Sir/Madam,

I have received communication of proposed adjustment u/s 143(1) a of Income Tax Act, 1961 three days back.

As per my Form 26AS I have received Rs. 5,296/- as Interest of Fixed Deposits with Bank.

They have asked me to response on the same with a period of 30 days from the date of issue of the communication.

Kindly guide what I need to do.

Thanks for your help.
