@loop315 Which image are you using? What hardware are you on? Please read this as agreed on signing up to the forums https://retropie.org.uk/forum/topic/3/read-this-first and give us some more info.
From your post, I can kind of deduce that as you got this Retropie "kit" for Christmas, that it was purchased with the SD card pre-loaded. That type of image is not something that the devs here will support and you'd be better downloading the official image and following the initial setup guide on the wiki.
