My itr is verified but i didn't pay the taxes

Hi all,

Every year I always get a tax refund but this time, I was liable to pay tax so it was different. As usual, I filled up the ITR 1 form online and also e-verified it. It was showing that tax is payable. I assumed that at the last step, it would ask me to pay the amount online but it didn't. Now I wonder what would happen. My friends say that the system doesn't allow you proceed unless you fill the challan information but for me it was all good.

Can I do something here to avoid re-filing ITR? Should I wait till they cancel it or can I do something now?

Thanks
