I want to sign out and save my info but do not find a header that says "my account"

TurboTax automatically saves your work as you go through the program.
To sign out follow the directions below:
•      Find Tax Home on the left side-bar and click it
•     Click Sign Out which should appear at the bottom of the left side-bar

no sign out button appeared when i clicked tax home

I want to sign in to my state return
