Hi Mohit,

As per the new guidelines for JEE MAINS 2021, candidates can adjust their fee for application fee to next attempt of session, if they were unable to appear in previosu session. Means, if you have paid the fee for February session but were not able to appear for same, then your fee will be adjusted for next attempt (March session).

As you mentioned, you did not appear for FEB session, but paid the fee for March session, so possibly your FEB session fee is getting adjusted for April session. Correction window is open till 4th April 2021, if you want to make any edits. For more information, visit here:
