 But it takes a lot of medical to be able to deduct it.

You can only deduct the amount of unreimbursed Medical Expenses you actually paid over 7.5%of your AGI.  And then all your itemized deductions have to be more than the standard deduction to get any benefit (so you would only be getting the benefit of the amount that puts you over the standard deduction).  And since the Standard Deduction is increased more people will not need to Itemize.

Medicare premiums paid for the year are entered as health insurance premiums in the Medical Expenses section of the program.

Health care insurance premiums and other medical expenses that you paid with out of pocket funds are an eligible medical expense that you can deduct using Schedule A for itemized deductions. However, only your total medical expenses that are greater than 7.5% of your Adjusted Gross Income (AGI) can be deducted. Your total itemized deductions reported on Form 1040 Schedule A must be greater than the standard deduction for your filing status to have any tax benefit.
