My iPhone is being tracked

Why do you say that?

You can certainly share your location with others, but have not provided any information, screenshots, or other information that would be concerning. Some apps like Life360 allow sharing your location too, but you would have to authorize that. Have you checked at Settings > Privacy & Security > Location Services and reviewed the information there?

For all we know, you got a text message that said you are being tracked and they want you to download some software to fix a problem you do not have.

As mentioned, the cellular networks track you all of the time. If they didn't, you wouldn't be able to make or receive phone calls. Apps can track you too, but only if you give them permission. Likewise, your phone will not share your location with others unless you have explicitly granted permission.

That leaves scams where people lie about tracking you, in hopes of ripping you off in one way or another.

Yes, quite literally all the time. It's how a cellular system knows when you've moved out of range of one tower and automatically switches you to the next nearest tower.

That said, I presume you mean something else, but you haven't provided any useful information.
