I posted a job application on indeed but the job opening post was made in around may is this a fake job?

Hi I’m a 15 year old kid and I recently wanted to get a job because my dad lost his job so I wanted to help. I found a job opening in market street and I filled out an application. It’s been around 2-3 weeks and I haven’t gotten a response yet I’m starting to get worried because I heard that indeed is a little fishy and I found out that this job post was made in around may 2020. I’m also worried because I entered my social security number on the job application. I showed my mom the website and everything but she said the website looked legit and it was the official HR United family website but I’m still a little worried. Am I screwed?
