XBox skin code on PC?

Play Fortnite on PC.

Have now received a xbox skin code and redeemed it on my xbox account on my Win PC.

However, there's no Epickonto for the xbox account.

How do I get the skin on my existing Epickonto?

Do I create a new Epickonto on my xbox account and connect the accounts or is it enough if I log in with my existing Epickonto through my xbox account?

Unfortunately, this only works if you have an Xbox

If I had basically…

You should log into your XBOX with your main account and then you should get the skin.
