Reporting income from Airbnb abroad

Many thanks for helping.

 

I live abroad and have Airbnb income through my primary residence as passive income. 

Did I understand correctly that since it's not earned income, I shouldn't include it in Foreign Earned Income Exclusion?

I get Foreign Tax Credit can be applied to all sort of income so I should use FTC right? But I should also have paid the tax already. If I know I won't pay it before the deadline what's my options?

 

Sorry there are many questions in this topic.
