Newbie: Just a loop as my next knit?

Hi, newbie here that needs help. Don’t know what I did, there is a loop on my left needle that I need to knit next but it doesn’t look like it is knit anymore? How do I fix this?

Thanks for your guidance.

Occasionally when you knit a stitch you don’t complete it and it ends up like that. Is there a strand of yarn behind it? It looks like it from the picture. If so use a crochet hook to reach through the loop and grab the thread. Bring it through the loop and drop the loop behind and put the new loop on the needle.
