Please help me in this sir

Bharath Hello Bharath,
In retrospect to the details provided by you, it looks like the correction of the particulars has been successful and they have been updated too. You don't have to pay any fees since you haven't been asked by the NTA to do so.
Best wishes again!
Regards
