The rho values are something that's only used by the Conic command itself as parameter for building the curve - once the Conic command has ended then you won't see rho value after that.

If you build an ellipse segment with the conic tool then there should be an object snap available to snap on to at the ellipse's center point. Make sure you have "Object Snap" enabled in the bottom toolbar then you can draw a point and place it there.

So for example if you've built an ellipse segment conic like this:



If you then go to draw something after that, if you have object snaps enabled you will see this little target marker where the ellipse center is at:



And then if you move the mouse there the "Cen" object snap will kick in and snap to the ellipse's center point:
