Are the dependants older than 18?  

Yes, dependents both are seniors.

What type of medical expenses are you trying to claim?  The deductible medical expenses are considered a non-refundable tax credit, meaning they can help lower how much taxes you’d have to pay.

To qualify, your household’s eligible medical expenses must add up to the lesser of 3% of your net income or $2,479. For example, if your net income is $60,000, all medical expenses beyond $1,800 are a credit against your taxable income.

Expenses for prescription drugs. I understand it is non refundable tax credits and my income is higher enough to include both my parents' medical expense, since 3% of my income is more than 2,635 and total medical expenses are much greater than 2,635. I don't understand why Turbotax don't include my parents' medical expense in total medical expenses I claimed under my return.
