I noticed something interesting: you can't submit the same project twice (but you can still edit it by uploading new versions on the itch page). Your username has a "Submitted" tag next to it, so you definitely submitted something; go back and click Submit again on the jam page, then go through the project dropdown. If you don't see [the project you intended to submit] in that dropdown list (and you know that the game's page is public), that means you already submitted that project and you're good to go.
If that's not enough peace of mind for you (not being sarcastic - it may well not be), then your best bet would probably be to try and contact one of the jam leaders on Discord and ask for verification.
... or I could stop being detective Batman and just click on the "Submitted" tag beside your name, which brings me straight to here: https://itch.io/jam/gamedevtv-jam-2024/rate/2739713 (I had no idea that was a link - I thought it was just a tag!)
Pretty sure you're ok XD
