Income tax refund of previous years excess salary recovered in current year.

Respected

I have been paid excess salary during the year 2010 to 2016 due to an un-due additional increment given by the department. As soon as, the matter came into the notice of the department, the department now started to deduct a sum of Rs.2500/- p.m. form my salary. I have already been paid Tax on this extra salary during the year 2010 to 2016 which now is being deducted from my current salary i.e. fy 2022-23. My question is how to adjust claim or get refund of tax on the recovery amount. Can my dept. reduce the recovery amount from my Gross Salary while issuring the Form 16 for the financial year 2022-23 or

Can I reduce the recovery amount from my Gross Salary while filling the Income Tax Return.

Kindly guide me in the matter & oblige.

Thanks.
