Ideally, you would have put the cut up raw turkey into a pot with cold water and seasonings. Bring it up to a boil and reduce to a simmer for an hour or so. Then remove the meat from the bones and return the bones and other non-meat parts (skin, gristle, cartilage, etc) to the pot and continue making the stock.
If the meat is already cut up into soup-sized pieces, they will cook in simmering soup in a matter of minutes.
