Hello Marshkal, You can simply say : "Where do you live in Poland?" "live" not "lived" if you are asking about a present state, the person is living now in Poland. You could also say: "Where about do you live in Poland?" If you ask where the person used to live in the past you could say: "Where did you live in Poland?"

"Where do you live?" - "Gdzie mieszkasz?". If you want to know where exactly someone lives, you can ask him: "In which city do you live?" - "W jakim mieście mieszkasz?".
