i have similar 5 cases of ay 19-20  unable to rectify as tab not open and above they are adjusting demand from present refunds

The other Rectification Request type will be made available soon . check if you can submit revised return 139 5, i think once you received notice under 143 1a , you have to reply against 143 1 notice only. 

no you can not, 139 5 is only after 139 1 till not processed, once processed and notice issued under 143 1a it will not accept, you can try on line or off line. but try in rectification only. check status,  service rectification new request select year AY  submit , on top it will show notice check do it allow you to rectify, check what it asking, revised ITR or just tax paid details,  let me know. may be it will tell you already submitted. help line is bull sh*t.

as per ITR 2 there is no option to file under 143 1 so you need to follow rectification tab only. previously you have already replied, what you submitted and how.

only rectification tab can solve your problem where you have to make correction.

previously you have already replied, what you submitted and how. if not done wait till tabs open and allow you to rectify.
