Help: videos playing in Premiere Pro faster than they are

I'm fairly new to video editing in Premiere Pro, and am trying to use it to create social media videos with video of me commentating sports, while dubbing in the audio of my commentary from a separate audio file.

I just uploaded a video into Premiere Pro, but when I drop the video in and begin playing it, it plays faster than if I just play the video in my computer's regular media player. I've changed the input settings, ensured the playback speed isn't set to more than 100% but it still plays like it's on fast forward. Is there some way to fix this without having to surgically pick apart the playback speed, which makes it harder to exactly sync up my audio and video files together?
