When you click on the little circle in the Info Window, you get a circle about the size of the average face located in the middle of the picture which, as you say, probably isn't where the face is. So you click in the center of the circle and drag it where you'd like.
Sometimes this goes awry, and you find yourself grabbing the whole picture instead of the circle. Photos lost "focus" on what you meant to click, and it thinks you're still in the Info Window, maybe. If that happens, I usually just click somewhere in the picture to tell Photos that's where I mean to be working, and then I can move it. Another plan is to click in the "Click to Name" field and type the name in first, and then you can move the circle.
The size of the circle is changed with the little knob on the side of the circle

to expand or retract the perimeter, with the center staying put. If you haven't already, you can type the name in then.
The size of the circle and the location of the center don't really matter-- you can arrange it however you like so the name ends up in a convenient place. Photos does not take manual IDs in consideration when identifying new faces.

So putting her name on her nose, for instance,

Still looks OK, since the circle isn't shown when viewing the image.
