Teen struggling with online entrepreneurship

I'm a 16 year old who is currently over summer break wanting to make a little extra money online cuz I'm currently unemployed and I have all the time in the world. It sucks seeing all these people online being the same age as me doing online side hustles making videos about it and growing communities yet I just feel stuck because I understand all the ideas I see all of the courses I would understand how to do all of the things but the past 10 times where I've tried starting any of these things I always reach a wall that just stops me right in my tracks it's the payment options or signing up for the apps because my parents do not want to help me sign up for anything because they don't believe that I can do any of this stuff and they want me to be reliant on them they're they will not help me with any of my finances or helping me sign up for any of these apps and all I have is the checking and savings account because I had a job before but that's all I have I want to start building a community I want to start getting paid I want to create something and I want to make something of myself but it's very unmotivating once I reach that barrier over and over again does anyone have any advice for me that they think would help?
