What state should I use for non-US address when filing taxes in Delaware? (I will not promote)

I am trying to file my corporation's taxes in Delaware. All the addresses that I have for the principal place of business and the director's addresses are all non-US addresses, in Europe more specifically. But the online form is still asking me for a US state even if I check the Non-US Address box. Should I just choose Delaware? (I will not promote)
