ITR Demand Notice
I filed ITR this year under new regime and paid all the tax with interest but after payment was successful it didn't redirected back to filing ITR so I had to close and I clicked on Pay Later and filed hoping that the generated payment receipt challan will be considered as at that time I wasn't aware that this challan needs to be added again in advanced pay section in ITR 1. So now I received demand notice with added interests. I responded as incorrect demand and stated the same thing as above and added the challan pdf and the required details but I haven't received any communication from them and it's 4-5 weeks. Anyone faced similar issues? Can somebody help on what should I do next ? The demand tax amount is around 80k which I paid already.

Yeah I had faced it 2 yrs back. Stupid Govt gave 500 crores to Infosys for this portal and yet their payment system is not integrated. This year again I was about to miss filling that payment info while finalizing submit, but I realized that I can go back and edit the tax paid detail.
It can take months of time now. So it just wastes time, but no need to worry except the waste of time. You can abuse them on twitter. Sometimes when you shout online, they lodge grievance and then their tech guys call you in a few days, though they may not fix anything.
As an alternative, you can first raise grievance on IT portal and then on cograms portal.

I have filed ITR2 actually and did the same thing and filed it, everified it and post that paid the remaining tax. I have the challan receipt but I couldn't add that because I made the mistake of verifying it earlier. My ITR has not been processed as of now, I was hoping that that challan payment will be considered automatically but I think I will receive the notice soon too just like you did l.
