I am 19 and I had a dental implant last year for $6000. My parents paid for it. Who gets to claim it???

If your parents choose to claim this amount on their tax return, they cannot claim it along with their own Medical Expenses. They must have you listed as a "Dependant" still, and the medical expense claim must exceed 3% of YOUR Net Income. This is called the "Medical Expense Tax Credit for Dependants Over 18", and more info can be found at this link: https://bit.ly/2OnqGtw

Here's how to claim this tax credit in TurboTax:
