tick..help!

Anyone have any idea what kind of tick this is? Idk how I could have gotten it but I'm guessing from someone else and it just crawled on to me cuz I don't spend a lot of time outdoors. I just so happened to rub behind my ear and it came off on my finger. I freaked and flung it but then found it again on my couch lol..now what do I do?! Ps it has soup on it because I drowned it in there so I wouldn't lose it while I got a plastic bag lmao.
