I ran into the same problem as bbqking692020. When I try to change the amount of my medical expenses, Turbo Tax tells me: "We checked, and this deduction won't affect your taxes"
In other words, I never get a chance to change my medical expense amount. I think this is a bug in TurboTax.
DawnC answered: "Medical expenses - search Schedule A and use the jump to link, you will land on RX costs"
I had to explore a bit to discover what I think DawnC is suggesting.
Here are detailed instruction of what I did:
Go to TurboTax's "View" menu and select "Forms". (Alternatively, press Control + 2)
Then in the left hand column, which lists all the forms, find "Schedule A", and then below "Schedule A" is "Medical Wks". Click on "Medical Wks".
The Medical Expenses Worksheet will appear, and you can directly enter numbers into it.
Hope this helps.
(Aside: In my case, my medical expenses were not high enough to change my taxes. However, I can enter a fictitiously high number, and see that the taxes do change. So it appears to be working.)
