You will have to tell TurboTax you lived in another state in 2018. The place to do this is in your Federal return, My Info, Personal information summary.
Click the blue Edit link next to your name and when the detail opens up, scroll down to Section 2. Tell us the state(s) you lived in. Then say Yes, I lived in another state in 2018 and enter California and the date you moved to Tennessee.
