Wrong UDIN has been uploded on income tax portal

There is no guidance on such errors. Please wait and watch. If there is any notice or communication, you can respond to it by admitting error and inform the correct UDIN. Do not revoke any of the UDIN. This is my view.

As such you cannot do anything now. Alternatively, write to AO for this technical mistake and inform him the correct UDIN. At least, it would be on record that you attempted to correct your mistake. Please take view from other experts also.

Did you get any solution regarding this? As we are also facing same issue.

I face the same issue, is there any solution to resolve this mistake, please suggest

I have a suggestion as I my self have committed same mistake. We can revise the 3CD and update the correct udin also for the other report UDIN which is being applied wrongly we can generate new din. Out client should not face any problem.
