I live in two states how do I itemize my deductions

for federal, it doesn't matter. 

for state, go though the state you moved OUT OF first.   In any event TT should be smart enough to figure this out. 

ps - you state "I live in two states".  Did you mean you "LiveD in two states".  

you can't live in two states - one has to be your primary residence....

I live in California for 6 months and then I live in Idaho for 6 months. My retirement income comes from California. I own and pay mortgage interest on properties in both states. That's why I asked about itemized deductions. I know there is not difference on the Federal return but not sure how to take the deductions on the state returns.

@vaknipps1954 - while you may live in both CA and ID for 6 months each,  certainly one of them is 183 nights and the other is 182 nights, adding to 365. 

Which state issued your driver's license? which state do you vote in?  the answer can't be 'both'.  That would support which is your primary state of residence.

So which one is your primary state of residence? 

complete the state return for the one that is NOT primary first. 

I suspect TT will figure out how to administer the deductions.
