Retirement tax questions

Hi, I just graduated in 2022 and I am filing independent.  When Turbotax review my return, error found and a form 8615 asked me to enter the child unearned income. I don't have unearned income over $2000 and I am not a dependent on my parents' tax return anymore. Why do I have form 8615 with my parents info is on the form?  I filled in $0 for child unearned income. Do I have to fill out this form? if not, can I just delete it? How? I rerun the smart check, the form kept coming back.  

The next error was asking me to check the box 'Launch Optimizer'.  I then checked mark it and my tax refund was reduced? I wasn't sure if the reduction is due to form 8615 or was it from check marking the Launch optimizer? Can I uncheck 'launch optimizer' How?
