AThe recipe I used was 16 oz white chocolate and 1 cup corn syrup...I used real chocolate but it was in 12 oz bags so I guesstimated...it has set up I just need it to be a little firmer...thanks!!

That seems like way too much corn syrup. The recipe I use is 12oz chocolate and only 1/3c corn syrup. You're probably going to have to work the excess oil into. it. Knead the heck out of it to try to incorporate it as best you can-- it's gonna feel like an oil slick-- cover overnight with saran wrap and knead it again tomorrow. It may take a few days to get it the right consistency.

AIt has a good consistency and feel...just a little soft...if it were fondant I would know to add powdered sugar or tylose...I'm just new at the chocolate clay and don't know how to thicken it up...I made it yesterday so I think it has set up for long enough

It's just going to take a while, could be overnight, could be a couple days. Modeling chocolate is one of those things that can't really be sped up.  Hope it turns out well!

If it was me I would remelt it and add more chocolate.
 

AAdding melted chocolate did the trick!!! Thanks a ton!!
