How to claim tax paid on regular assessment

For the A.Y. 2010-11 i have received the Assessment order with Demand Raised by AO. Subsequently we have deposited the Tax of Rs. 62887/- under 400 - TAX PAID ON REGULAR ASSESSMENT. Lateron we have filed the rectification and after the rectified return we found that there is nothing due to pay and Rs. 62887/- already deposited is excess of net tax.

Now it is not under the head 100 - Advance Tax as well as not 300 - Self Assessment Tax. Rs. 62887/- is also shown in Form 26AS. Now how can i claim Rs. 62887/- i.e. tax paid on regular assessment. As there is no option available under the Form ITR - 4.

Should i treat is as a Self Assessment Tax and file a rectification online or something else. Please reply it's urgent.
