If you see a message that you need to sign in to iTunes
If you created your Apple ID on the web and see a message that you need to sign in to iTunes, follow the steps below for your device:
* On iPhone, iPad, or iPod touch: Open Settings, then tap Sign in to [device]. Then sign in with your Apple ID.
* On Mac: Choose Apple menu > System Settings (or System Preferences), then select Apple ID and sign in with your Apple ID.
* On Apple TV: Sign in to the App Store, iTunes Store, or Apple Music with your Apple ID.
* On a PC or Android device: Go to tv.apple.com or music.apple.com and sign in with your Apple ID.
If you continue to see the same alert after going through the steps above, the next best option would be to reach out to Apple Support directly from this link here: Contact - Official Apple Support
We hope that's able to help.
Have a great day!
