How do I copy & paste a phishing email to the Yahoo reporting form?

This morning I got an email from tycarter@u.washington.edu telling me he saw my car for sale ad posted on his account on Craigs'list, and I better remove it or "I will re...... I HAVE no car for sale, and never posted a car on Craigslist. Below the email, in lavender where it can be opened, it says: https:cincinnati.org/cto/ I don't know who the H tycarter is, I never posted an ad in Washington or Cincinattie. I have one ad in Mankato, MN. I reported to Craigslist, but need to copy and paste the email onto the Yahoo report form to submit. I don't know how. Everybody watch out for tycarter, and don't open the email!!! I didn't.
