TurboTax is requiring me to enter information about an HSA, but I don't have an HSA. What should I do?

If you have a W-2 form, check Box 12 to see if there is an amount with a code W. It means you have made a contribution to your HSA account either through paycheck deduction or employer contribution.

This might be the potential reason why you are asked to enter information about an HSA.

I do have a value with code W in box 12 but I have never even heard of an HSA. I don't have one.

Check what benefits your employer offers. 

Health Savings Account (HSA) is a type of savings account that lets you set aside money on a pre-tax basis to pay for qualified medical expenses.
