Not sure what your question is, since you didn't specifically ask a question. maybe this will help.
Your dependent is required to file their own tax return. Assuming they are under the age of 19 on Dec 31 of the tax year, *OR* a full time student in 2020 for any one semester that started in 2020 and under the age of 24 on Dec 31 of the tax year, your dependent is *required* to select the option for "I can be claimed on someone else's tax return" when your dependent is completing their own tax return.
You the parent will still claim that dependent on your own tax return.
