Attempted to season my new cast iron pan and was left with a ring
From the look of that, I'd say there's two possibilities.


your burner is too small, and is heating the pan in the middle only, producing the ring.  The solution for this is to heat it in the oven as explained in this answer.
as Tetsujin suggests, you may be using too much oil and it's pooling in the middle and burning.


In either case, your next step is to scrub the pan to get the burned and uneven oil off.  I suggest using coarse salt with a little vegetable oil as a scrubbing mix; I get my pans smooth this way.  Then restart your seasoning.
