My iPhone does not pop up on iTunes can it be because it is disabled ?

Your Apple ID account is what is disabled. See 'Your account has been disabled in the App Store and iTunes' https://support.apple.com/en-us/HT208856. This link says: "There might be a problem with the payment method that you have on file. When you see the message, don't try to edit any of your account information. Instead, contact Apple Support for help.”

Use the Apple recommended support link above first.

And, if necessary, go here is how to contact iTunes worldwide support via text or chat using this link https://support.apple.com/choose-country-region/itunes After choosing your country, see the heading Tell us how we can help.

If the phone is disabled, it isn't because your account is disabled.

iTunes doesn‘t recognize your iPhone, iPad, or iPod.
