On "Your State or Country of Domicile" page,it asks "Where were you domiciled?" This is vague:i was domiciled in previous state before domiciled in new state.Which i put?

TSIA. I was domiciled at previous state and then domiciled in new state after establishing residency. But the question just asks "Where were you domiciled with no context or other details".

You can enter the state of domicile at the end of the year.  Since you were domiciled elsewhere previously, you may have to file a part-year resident return.
