Itemizing requires that you not take the standard deduction, 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).
If you missed out on a deduction for medical expenses in past years for any reason, even simply not knowing about the deduction, you can file an amended return for the prior three years. Filing an amended return requires completing Form 1040X to claim your additional deduction.he medical expenses deduction is an itemized deduction, which means you can't claim it unless you give up your standard deduction and itemize. Plus, the medical expenses deduction isn't a dollar-for-dollar deduction.
