Hey Celia, I saw the trilobed leaf, but in looking for a good seedling pic ran across this on the UC-Davis site for Ipomoea purpurea so didn't really consider searching beyond images.
"Mature tall morningglory is a vine with long stems that branch, twine, and climb. Leaves are often heart shaped, sometimes three-lobed (both leaf types can occur on the same plant), and mostly range from 3 to 5 inches (7–12 cm) long. Leaves are alternate to one another along the stem. Minute flattened hairs usually cover the leaf surface, but sometimes leaves are nearly hairless. Japanese morningglory is similar in appearance but instead of flattened hairs, has erect to ascending hairs on the leaf surface."

I saw a listing for I triloba, but I do not think it is anywhere near what Jaym1818 has.

But, given what he ordered and what he got, it could possibly have some Ipomoea hederacea (Ivy-leaf Ipomoea) mixed in
