Signing Savvy, Your Sign Language Resource

Is this how you say:  "Where?"  Or, is this only used in a sentence when answering that question, like "Where I used to go for coffee."?

What about government where the states share power?  How do I sign this "where"?  Can you add it?

I am writing a sentence for class and am wondering should the word where be in it.

English: I have always read "Home is where the heart is."

Gloss: I HAVE ALWAYS READ, HOME WHERE HEART LIVES.

I am not sure if this is correct but could use a little guidance. Thanks!
