Hi Snakecharmed,
Welcome to the Roku Community.
Congratulation on your new Roku TV! Let us help you add these channels to your new Roku TV.
Please be advised that when you add an app to your Roku device, you’re actually adding it to your Roku account. As a result, the app will automatically be added to all Roku devices linked to your Roku account. The same goes for when you remove an app, it will be removed from all Roku devices linked to your Roku account.
May we ask if have you successfully activated your Roku TV? If so, kindly check your list of apps on the home screen and you'll be able to find those channels.
Additionally, if you wish to add your Roku TV connected to your Roku mobile app, learn more here: How to connect the Roku® mobile app to your Roku device over Wi-Fi
Hope this helps. Please let us know if there is anything else we can assist you with.
Regards,
Nimfa
