Home videos missing from TV app

Hi, I currently have the 2022 MacBook Air and used to have a laptop with all of my old videos I made on iMovie on the home videos feature in I tunes. I read a bunch of questions here about this topic and was able to find where the home video tab is in TV, but my videos were not there. I am wondering where they could be? please let me know, thank you! I still have my old laptop and im wondering if I have to import them manually.
