Challan to be used to pay outstanding tax

Hi

I'm a salaried professional and I switched jobs around Dec 2013. I did not declare salary from my previous employer with the new employer and as a result the TDS for the salary I earned with the new employer was far lower. I'm filling the ITR online and the ITR form has calculated an outstanding tax that I need to pay. Can you advise which challan do I use to pay this outstanding tax amount

Regards
