The actual address is pink?  If so, did you double check the the little box for a foreign address didn't accidentally get checked?

not checked

You've double checked the address is entered in the US address section, rather than the foreign address section?

yes

Have you tried deleting the entire address and re-entering it again (in the US address section, and without the little foreign box checked)?

I'll try that...this is a town on island of Molokai, Hawaii. Entered Zip code and correct Town name appeared. i wonder if PS isn't aware that Hawaii is a US State.

Is there a Foreign Earned Income Exclusion (Form 2555) in the return that might be triggering something weird?

nope,,, only difference from last year is taxpayers moved from Oahu to Molokai and primary taxpayer died in 12/22. I entered date of death.
