How to rectify ITR of previous AY

This discussion addresses the challenge of rectifying an Income Tax Return (ITR) for AY 2020-21, even after it was previously revised and intimation/rectification orders were issued. The user is encountering an error on the portal stating 'UNLESS LATEST ITR TO BE PROCESSED YOUR REQUEST WILL NOT SUBMITTED'. They are seeking clarification on whether this means they need to process the latest ITR for AY 2023-24 before they can submit their rectification request for the earlier year.
