What do I do if I turbo tax has a different total than I do for my medical expenses?

When you entered medical expenses, you should not have entered Medicare Premiums, as you know they pull over. You would enter medical mileage which the program turns into a dollar amount.  You will need to review your forms and entries to find anyplace that some expenses may have been entered twice.
