Should I Cancel Couch?

I ordered a couch for my tiny living room but now I’m worried it won’t fit (80”x40” without the 40”x40” ottoman)! Can you help me get a good layout for my living room so I can order the right furniture? Each square is supposed to represent a square 6” but it’s obviously not an exact rendering lol but it’s fairly close. I want to keep the TV on the South wall and the piano on either the north or eastern wall but open to other changes. Thank you for any help/ideas!
