The good news is the chocolate doesn’t fill up until you can get some candy down there, the hard part is getting down there. Oh and that jelly you are looking for, it’s under the 3 chocolate pieces at the bottom in the middle column and it’s double jelly. You really need a vertical striped candy to plow through to the bottom, single matching will be very difficult.

Try to break the block above the second column from either end. The chocolate will stay somewhat contained as long as candies don’t touch it. Try for a striped/wrapped combo low on one of those sides to completely get rid of the chocolate. (If you prefer to battle the chocolate, break the top row of blocks and make a vertically striped candy match.)
