Yes part B is deductible if you itemize and don’t take the Standard Deduction. I don’t know about the other parts. If you enter part B when you enter the SSA-1099 it will automatically flow over to Schedule A.
But 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.
