If your iPhone, iPad, or iPod touch is lost or stolen

Use the Find My app to locate a missing device or item

Mark a device as lost in Find My on iPhone - Apple Support

When you log in to https://icloud.com/find does it show your phone, but say it is offline? Or doesn’t it appear at all? If it doesn’t appear at all then Find My is not enabled on the phone. If it says it’s offline then either the phone doesn’t have a data connection or it is powered off.
