Yes, you should be able to deduct expenses for a functional medicine doctor (alternative medical treatment) and for travel expenses related to medical care.

To claim the medical expenses deduction, you must itemize your deductions. Itemizing requires that you do not take the standard deduction,($12,200 if you are single or use married filing separate status,  $24,400 if you are a married filing jointly or $18,350 for head of household)  so you should only claim the medical expenses deduction if your itemized deductions are greater than your standard deduction TurboTax will do this calculation for you.
