outr=sit or live？

Selam dostlar.Yesterday when I scroll Instagram,I found a video which expressed "Nerede oturuyorsun?" means "where do you live"and you should reply it with "Ankara'da oturuyorum",etc.But my language book told me "oturmak"means "to sit"instead of live in some where.So I wonder how to ask someone "where do you sit" ? Teşekkür ederim。
