Notice u/s 139(9) - Problem in e-proceeding

Sir/ Madam,

I got a notice u/s 139(9) advising me to correct my I T Return for the AY: 2020-2021 after incorporating P&L and BS -as per law I am required to maintain accounts u/s 44AA - which I did not give in my original return .

Now, I downloaded ITR for AY 2020-2021  and revised my earlier Return - the options available are: 139(1), 139(4) , 139(5), 92CD and 119 (2)b.

I chose the option "u/s 139(5) and duly filled up. While uploading the X M L. through e-proceeding tab, it is saying" You are not authorised to do this" , Last date of submission of reply  is 12.10.2021.

Kindly advise me what to do.
