E-filing after due date

No question of any interest or penalty, provided filed before march, 2018; but you would not be able to revise it..........

Thanks a lot for the reply sir.

I managed to stay awake last night and filed it. The site was so slow, I almost thought of giving up!

That's best thing you did............ though the time period likely to be extended......

But one can relax now !!!!!!
