Fix deposit interest

Hi,
I transferred money to my wife's account and done FD in her account.
There she has earned interest and 10% tax was deducted from there.
I came to know that, I need to add that fd interest earning in my earning.
So question is
-do I need to claim return (already deducted tax from wife's account) by filing wife's tax return and add interest in my earning and pay tax?
or there is any other proper way?

Thanks for help.
