Good morning irishallday!
I see that you're attempting to restore the iPhone, but the download file is taking a long time to complete. I'll be happy to help out.
Depending on network speeds and other factors, it can be normal for the download to take some time to complete. According to If you can't update or restore your iPhone, iPad, or iPod touch - Apple Support, "If the download takes more than 15 minutes and your device exits the connect to iTunes screen, let the download finish, then repeat step 3". The step 3 needed to be repeated can be found in the resource linked above as well.
Take care.
