Medical parking fees

Parking costs while you visit a doctor are usually deductible as part of the itemized write-off for medical expenses. Add up all your deductible expenses, then subtract 10 percent of your AGI. Whatever remains is your write-off.

TurboTax will handle all those calculations for you and determine whether they will count.  You need to enter all of your medical expenses and TurboTax will determine how much, if any, is allowed.  When you go through the medical expense section, you will see a data field for medical mileage, parking, etc.    You'll also have to have enough total deductions of all categories so that you can itemize deductions.
