You should show the accured interest in your ITR because bank follow accural basis and deduct TDS on the same.
And if you don't show the interest in your ITR than there will be mismatch of your IT return with 26AS.

If bank is deducting TDS and the same is reflecting in 26AS the best way is to go according to 26AS. If not you may either show interest on accrued basis or on maturity also. But it is better to show on accrual basis every year.
