Hello
If your iTunes on your computer does not detect your iPhone, you might have the Apple Mobile Device Support service turned off on your computer. Please refer to this Apple Support Article for more information on how to resolve your issue.

if the issue persists, uninstall all apple software from your computer, reboot (turn off, then turn back on) your computer and then reinstall iTunes.
Hope that helps
