I am Danish. I moved back to Denmark September 2015. I did already file 2015 Taxes. Now Turbotax ask me to file taxes for 2016. Why? Did an error occur?

I am Danish citizen. I finished my internship in the US in August 2015. I moved back to Denmark in September 2015. I already filed 2015 taxes last year. 

Now I get a notification that I have to file taxes for this year again. Why does this happen? Can I just ignore this, or what action should I take to correct possible errors that have led to this mistake?

Thanks in advance for your advise.

You are misunderstanding the Marketing notice ... no where does it say you must file a return.  It is inviting you to use Turbo Tax again for 2016.  Ignore the commercial if you don't need the product.
