Foreign tax credit - Other gross income - country

In TurboTax 2020, when reporting foreign tax credit, I first choose income type. In my case "Passive income", then after adding a country, there is a screen asking me "Other gross income - [country name]".

The question is what it means "Other". Is it other to the "Passive income" I marked before or is it "Other" to forms 1099-INT, Form 2555, and Schedule K-1?
