Your medical expenses may not be "posting" to your tax return for a couple different reasons.
Regardless of the type of medical expenses you have entered, the total dollar amount must be more than 3% of your net income to have an effect on your tax return.
Also, you will not see any difference if your taxable income is below $11,635 and "not taxable".
