Apple TV 1

I am trying to sign into itunes on Apple TV 1, however, it's asking me for the two step verification process. After I have entered the email address, password, I get a prompt to enter a verification code. However, Apple TV doesn't allow me to enter the verification code on the screen. As I get the message "Could Not Sign In - Apple ID vertification code is required to sign in. Type your password followed by the verification code shown on your other device". There is no option on the TV screen to enter the code.

The next things I tried to do is disabledTwo-Factor Authentication on Apple ID. I've tried to do this on the iPhone and on Apple Manage ID website. However, it looks like it's impossible to turn the two-factor authentication off. As it doesn't allow me to disable it (see pics), as there are no options?

Any suggestions how I can sign into itunes on Apple TV? I'm very frustrated!!!!
