Advance Tax - Senior Citizen

A.Y. 2021-22. A person became senior citizen on 31.12.2021. Person has Income from Salary and Other sources(FD interest). Advance tax is levied on the FD interest portion of the income. While filing return, no interest on 234 A B C was levied. However later on demand came for interest of 234 A B C. The demand was fully paid. However, senior citizens are not supposed to pay Advance Tax if they have income only from salary and other sources. So, in this case demand amount was not correct. Is there any way to get refund of the amount paid ?
