Self Employment Health Expenses

When I enter my medical insurance premiums and my long-term care insurance premiums in the Expense Section of Turbo Tax, it does not appear to reduce my self-employment income at the bottom of the page.   The bottom of the page recognizes my other expenses like office, supplies, etc., and indicates my income has been reduced by those expense amounts but it does not include the health expense amounts in reducing my income.  Why is that?
