In the interview, I erroneously checked both myself and my spouse as having HSA's on the "Tell us about health-related accounts you had in 2019" screen. After entering data for myself, I realized only my spouse has an account. So I unchecked the box that I had an HSA. But TurboTax remembers all the entries I made (contributions, withdrawals) and adds them to my wife's contributions. I had to re-check the box, zero-out my entries, and then go back and uncheck the box.
This is probably a bug.
