Filing return once notice u/s 139(9) was received

Hi,

When I filed IT returns for the first time, I had a tax due. But, I filed the returns without paying the due. Few days back, I received the u/s 139(9) notice from the IT department. Now, I have the paid the dues online and got the Chellan ID Number. When I am filing the returns from the IncomeTax website with File returns under u/s 139(9) in e-file tab. So, to proceed, I have downloaded a fresh ITR-1. In that, what to fill under "Return filed under section"? It should be u/s 139(9) or something else? And, what should I fill for "Whether Original or Revised return"?

Please help

Thanks
