Form 16a and form 26as conflict.

Hi, In my ITR 1 i have to show income from FD interest. While cross checking my Form 16A with the Form 26AS i found that there is a difference in amount of Interest Credited and Tax Deducted in Form 16A with the form 26AS. As per 26AS i found that the interest part is about 10 thousand more and tax deducted is also with respect to that. Why is my Form 16A shows less amount than given in the 26AS. ? Please help! . Which one should i show in my ITR 1 as Income from other sources? Thanks Anil
