medicare part B deduction for federal and state

Hello,

I was wondering how deducting medicare part B works for Federal and Tax returns for this year.  I do not receive social security because I get a pension from CALSTRS.

Does Turbotax automatically insert the amount? Is it a set amount? I have been paying almost 600 a month (income increased due to the sale of my home in 2021) so my medical expenses went up considerably.

I am not sure how to do this for 2023 taxes due in 2024.

I would appreciate some advice.

Thanks

D.
