ITR rectification due to revised Form 16 by Employer

Thanks. Due to wrong declaration of income under original form 16, i got refund during last week based on original form 16 . Now revised form 16 released today with correct ESOP and income in form 16 is trippled.i think i need to return or pay back refund which I claimed based on old form 16. So can I proceed with revised e-file?

ESOP is taxable under salary (perquisite) and no question of refund.

Benefit of cost can be claimed at the time of sale of shares..
