Income Tax on Medical Expenses :Under Section 80D

Hello Gurus

Need you advice on following case:

In FY19-20, a person was under medical insurance of 2 Lacs sum-assured (Premium was 37K for that policy). This policy was on 80:20 copay, means person has to pay 20% of bill (along with other non reimbursable expenses).

In FY19-20, total hospitalization expenses were 3.5 Lacs. Out of 3.5 Lacs, 2 Lacs were paid by Insurer and remaining 1.5 lacs was paid by kin of that person.

Now, while filing the ITR, what will be the best way to show these premium & medical expenses, in case ITR is filed by person's Son?

Thanks in Advance

Looking for some positive feedback.
