Playstation Network Problem CoD Warzone?

I downloaded CoD Warzone. I wanted to play it, but then I get the error message

Can someone help me?

It says what the problem is

You are too young for the game. I guess that's what your parents did.

No I'm not, I'm 19 but I'm not a family leader. It was set that I can play anything from 18. Do I have to set something else?

But I don't know where to set it.

In the settings! Read that you are 19! A bit of independence! Especially with such problems!

I searched but did not find. In the settings, I set everything so that I can do everything. Its not possible.
