I'm happy to say I was able to find your card here. It wasn't in regular Hoops but the Hoops Winter product. Unfortunately if you see a Panini non-base set checklist that includes regular numbers instead of letters, it's almost certainly incorrect (even straight from Panini) because they number things with letters/initials the vast majority of the time.
That said, the easiest way to find an unknown card here remains looking up the player, clicking the "Filters" link, and filtering by the card number you have.
