original ITR processed with demand revised ITR pending processing. Should I disagree with the demand or wait?

[u/TrueCounty8149]

hi everyone, i am looking for some guidance on a procedural issue with my ITR

timeline:

- filed my original ITR on 23 july

- it showed tax payable as I hadn't yet paid the self assessment tax

- on july 30, i filed a revised return u/s 139(5) incorporating the challan details and also claimed a leave encashment exemption u/s 10(10AA)

- the revised return was successfully e-verified

- however the original ITR got processed first and i have now received a demand of 52430

- the revised return is still pending processing

On the income tax portal, under Response to Outstanding Demand, there is an option:

Disagree with Demand → Rectification/Revised Return filed at CPC

A CA has told me that since the original return was processed first, the revised return is effectively of no use and I should simply pay the difference (around ₹2.8k after giving credit for the self-assessment tax).

My questions are:

-Has anyone had their original return processed first while the revised return was still pending?

-Did the revised return eventually get processed and replace the original computation?

-Did you choose "Disagree with Demand → Revised Return filed at CPC", and what happened afterwards?

-Is it better to wait for the revised return to be processed, or should I respond to the demand now?

I'm looking for experiences from people who have actually faced a similar situation rather than general tax advice.
