Came Across Cp On Accident. I Am A Minor So What Are My Next Steps And Should I Be Worrying As Much As I Am Rn?

Location: Georgia (United States)
So, i (f14) did have a post like this earlier and it did get taken down so now that I've had time to calm down a little, i still have several questions regarding this situation. I've read some articles about this kind of not-so- great stuff being found on the normal web and on engines like Opera (which was what i was using) and I wanted to check in with some people who maybe have more info about this than i most likely ever will if that makes sense. Also, yes i am a minor, I just guess I'm more mature than i was 4 years ago if you look at my first comments on posts. And i do know some basic sort of computer terms (for clarification)

To the chase: I was just trying to find an emulated version of the classic Sonic the Hedgehog game and i ultimately did or so i though. I got the file off of the site and seen that it was downloading to my google drive as .ZIP folder. Stupidly, i made the decision to go see what it was and unzipped it. I was met with something horrifying to say the least. It was CP.

Now, with it being an early school morning, i just closed my laptop out of sheer shock and at a later time, deleted the file. Google a few days later, had shut down my account and said that Cyberline had received a tip about this incident. I did a virus scan and factory reset the computer (for safe measure) and also reported it, albeit a week or so later since i had no idea how to report things of that nature and was scared that swat or something would bust down my door or something like that. I've already told my parents. it was only one file and i did see that there is a priority list or something of that sort.

With that being said, i also did see that possession is also illegal but i had no intent to possess/ share/ solicit this kind of material by any means. I just hope that maybe I'm worrying too much since i already feel like I'm all over the place mentally.

Edit: don't they also monitor your activity for about a year? Js curious since they're gonna see A LOT of sonic related stuff, RecRoom and school essays lol
