Thank you @DianeW777 , that was the missing step and fixed the issue with the correct 30 yr depreciation.
I was assuming selecting the first screen's "Foreign Country" option would trigger this non-US workflow and 30 year depreciation method, but I see now that only when selecting the 2nd set of screens you pointed out does the logic actually kick in (the initial 'Indian reservation' and 'disaster area' text made me skip over the rest of the selection).
MANY THANKS for your valuable help and expertise with this. It's helping 2 other TT users I'm working with! I appreciate the time you spent to investigate this.
