Issues with domain email forwarding

I initially set up my site, ArtCultured.com, with WordPress.org around a month ago. I wanted to be able to have an email associated with my domain which would forward to my Yahoo account. I was able to set this up successfully, but since I am new to the game, this was a big undertaking for me and I have forgotten what steps I went through to set this up.

There is no link anywhere that takes me to my domain email, and as I set this up through WordPress, I figured there had to be…Am I just totally blind? I don’t know what I’m missing – how could I set up an email and then never be able to find it again?
