When I use Alexa to trun off the tv :Alexa, Turn off Living Room TV". it only goes to the green Optic Screen asking to press OK to continue watching. Can I get Alexa to actually turn off the TV?
I don't believe this is possible as Alexa is controlling the Optik STB but AFAIK the STB cannot send a signal to your TV to turn off. I don't believe the STB supports HDMI CEC:

When you use the remote it's using the normal remote commands to turn off the TV and STB.
