Gluten Free/ Celiac Deduction

I have a dependent with Celiac, requiring gluten free food. The extra information links within the TurboTax program does not help me figure out where the excess cost is claimed for deduction. So, I need to know if excess cost can still be deducted for 2024 (most recent community info is 2019)? 

 

If excess cost can still be deducted, which section does that cost go into (again, the help topics within the program do not help)?

 

Final question is not as simple if this still applies. Gluten Free to regular cost is not an apples to apples comparison. My example will be breakfast pastries, aka Pop Tarts. The gluten containing pop tarts at the store contain 12 pastries (6 packs of two). The gluten free alternative contains 4 pastries (4 packs of one). Gluten containing price for 12 is $1.97, and the gluten free price for 4 is $4.48. The problem is, this price comparison is 12 pastries to 4 pastries. So, 4 of the gluten containing pastries (one third of box) would be $0.66. Would my excess cost on this transaction be $3.82?
