Hi - It's possible. When you enter the marketplace information into TurboTax, a reconciliation takes place to see whether you got the right amount of help to pay for health insurance (called a subsidy). The calculation uses the income that you entered into TurboTax. Generally speaking, if you made more money in 2016 than what you estimated when you signed up for the plan way back during open enrollment, you typically have to pay some of the subsidy back. Hope this helps!
