difference in 26AS and interest income certificate

I have found a difference of rs. 1302 in my 26AS nd interest income certificate(Form 16A) which i recieved from my bank. Although TDS deducted was same in both the cases. When i gave for rectification to my bank, they told that they are not able to trace the entry which was clearly visible in 26AS certificate and interest income certificate (16A). Althoug i have filed ITR, but i am not able to fill the revised ITR since the entry is not traceable. Kindly guide me that what i need to do, & how the entry will be rectified.
