Owning some bitcoin and stock but sold them. Got a 1040 form, I have no income but can be claimed as a dependent. What do I do?

I bought some stocks on CashApp on June 18, 2021, and sold them on October 21, 2022.  I also purchased some Bitcoin on Dec. 06, 2021, and sold them on October 21, 2022. I received a digital 1040 form, I have no income and am a single mother to two kids. I can get claimed on my parents' income tax though. What do I do? Can I file on my own with my dependents or not?
