Deductions & credits

I don’t know what you mean by change the method. The fact is, that even though TurboTax asks many granular questions about types of medical expenses, all of your claimed medical expense deductions go on one line on the tax form. So it doesn’t really matter what you put in TurboTax, except that if you are audited, listing the granular items in TurboTax might help you to assemble the records that you need for your audit.  Of course, you should always be keeping accurate records of your deductions because, if you are audited, you don’t get credit for any deduction that you can’t prove.
