120fps playing back choppy and too fast! Premiere Pro

I shot some footage with my iPhone 8+ at 120fps 1080p. When I drop the footage onto my Sequence it plays back very choppy and too fast. Seems like it's playing back in 30 fps. I've googled everything I can think of but no advice so far has fixed this. I've interpreted all of the clips to 24fps and 120fps and neither changed anything.

I've made multiple projects with my iPhone at 120fps using PP and all of them were completely fine. The footage played back at 120fps super slow-mo. I didn't do anything different this time but now I'm having this problem.

I'm trying to get my footage to play back at 120fps slow-mo.

Please help.

Thanks,

Nick

    Re-reading your original question: if you follow this video, do you receive the same results?

    Doing this interpretation method, you can use slow-mo or normal speed and can get your adjustment layer to match your source sequence. (note in the video I'm using 100fps footage so I'm interpreting to 25, you're using 120fps so you would interpret to 24 or 30.

    Phones record in VBR which NLE's notoriously have a hard time using. First, I'd try transcoding to a CBR intermediate format. Otherwise, bring your footage into a new sequence and check that your sequence settings match your source (or your preferred output destination format) and interpret as needed.

    I am ridiculously new to PP and film editing. Your response is a foreign language to me. I'm sorry.

    However, I did check my sequence settings and they seem to be the same as what I shot at. 120fps.

    When I added an adjustment layer to my sequence, it would only allow me to choose 23.97 fps; so I am assuming PP thinks that my footage is at 23.97fps. This would make sense why it's so fast and choppy.

    Any way to fix that?
