I believe that in prior versions of Turbotax when you entered a medical expense you entered the date of the expenditure. Then you could choose the 12 month period to optimize the annual expense. Medical expenses that were outside the 12 month period chosen would be carried forward by Turbotax to the next tax year. Now it seems the user must choose a 12 month period and then enter the expenses only for that 12 months. Turbotax does not seem to get better year over year in this regard.
