Dear Mohit,
If you have given 15G, the bank will not deduct Tax. However, they will show interest credited to you in form 26AS. In case the actual interest received by you is lesser than the one shown in 26AS due to premature withdrawal, you may wait to see whether bank rectifies the same or else you can get a separate certificate from the bank for the actual amount received by you towards interest. You can show this actual amount in your return and not the one shown in 26AS. If there is a query from the department, you may explain accordingly. No need to worry.
