Twitch bypassed minimum age - request support now?

I have a question about Twitch and its minimum age, I created my Twitch account before I was 13 and therefore probably gave an incorrect date of birth (year) (I'm not sure, but otherwise I shouldn't have created the account or?). Now I'm over the minimum age and am streaming again (-er) on Twitch.

Now to my question: Do you think I could write to Twitch Support and ask about my date of birth or ask for a change if the date is wrong? Or would Twitch be able to block (ban / delete / etc.) My account because I violated the terms of use at the time?

Have you had any experience with this / heard of a similar case?
Should I write to Twitch Support about this?

"Or would Twitch be able to block (ban / delete / etc.) My account because I violated the terms of use at the time?" "

Correctly. That and nothing else

Should I still contact you or just leave it at that?
