Mediclaim deduction

Hello sir,

My query is as follows:

Income Tax return filing for FY 2019-20 (AY 2020-21)

Mediclaim renewal is due on 22/3/2020.
Premium paid Rs. 25000/-
Policy mentions period as 23/3/2020 to 22/3/2021.

Can one claim this deduction for FY 2019-20?

or based on policy period, it is to be considered for FY 2020-21?

Kindly revert.

Thanks
Suraj
