I sign in the 1 year free Apple TV how do I access Apple TV from my tv

If you have already accepted the offer on your iPhone, and if Apple TV is not showing up already, reboot your Apple TV and your other devices logged into the same Apple ID, and you should then have access.

(This if you’re not on some random TV or Smart TV, as listed above. If so, and as mentioned above, the TV will either need the Apple TV app downloaded for your particular TV, or you’ll need to connect and use Apple TV hardware.)

You need either a smart tv with the apple tv app on it, or an appropriate device with that app.

Fire TV stick, Apple TV device, Roku - are all examples of devices that can install the apple tv app.
