For my deductions I have a medical expense but the only thing I put down is what was taken out of my SSD Part B.

If you have additional deductions to report, you may itemize, but only if all your deductions, less any limits imposed, will be greater than your standard deduction. 

Enter in all your details in the Deductions & Credits section and TurboTax will calculate which one is best for you. 

For more information, see: How does the Standard Deduction differ from itemizing deductions?

But it may still benefit you for State.  If it was already listed on your SSA-1099, you should not have entered it again.
