Thank you for reaching out!
This is in the Foreign income section. I am almost done with the preparation, but it will not let me file as there are items to review. This is one of them related to form 2555 from what I can see. I believe it is section 28 for foreign housing expenses entry where there is a drop-down to select a country, and Bulgaria is not on the list. Last year my return was similar and it looks like I was able to claim those expenses somehow.
