Have you entered all of your other itemized deductions yet?
TurboTax starts off giving you the standard deduction. Once you
enter enough of your total deductions (allowed medical, taxes, interest,
charitable donations, deductions subject to the 2% floor, etc.) that it exceeds your standard deduction, then TurboTax
will switch to itemized deductions on Schedule A. Medical is further
limited; only the amount over 10% of AGI (7.5% for age 65 or older) will
count--and only if you can itemize deductions.
Have you entered enough total deductions for TurboTax
to switch from standard deduction to itemized deductions? If you
haven't entered all your deductions yet, wait until you've entered the
rest before deciding how TurboTax is handling them. Until the total
surpasses the standard deduction, they won't start to count on the
Federal side.
