Same issue! I called TurboTax support and they did not know about this question. They said the form comes from IRS and this is new. I didn't answer the question but clicked the back button. Now it's not showing up anymore and letting me continue. It was suggested to click on the 'Feedback' link at the very bottom of the screen to tell TurboTax how I feel uncomfortable with this question. This feels like intimidation and persecution of immigrants regardless of citizenship.
