Help! How do I find my mistake?!

ok, so I am still going at the luna moth shawl (I stopped for a few months because of this issue!) and I have one extra stitch. I am on R 23 second or third repitition, and I have narrowed down where the error is. It is between k4,yo,k3. I think it is where the yo is but I can’t see the mistake. about three rows down is where I started a new ball and I think I see an error there but I am not sure what to do about it. I am going to try to upload a pic…Thanks everyone!
