Why does TT charge $21 for a simple tax return just because someone wants to claim medical expenses? It is horrific to charge disabled people more than the abled.

TurboTax Free is supposed to cover simple taxes. The things they charge you extra for are almost all either additional sources of income, or expenses that do not typically affect the poor, like donations or employment expenses. The ONLY exception to this is medical expenses, which disproportionately affect the poor and disabled. Why are people with a decreased ability to cover these costs responsible for them? How do they justify this? Why did this change? This is barbaric.
