Do I Have A Adult or Child Account

Hi there!

I have a question... I have $85 in iTunes Cards (Christmas presents! 🙂) And I want to load up my apple id with them all... But I am afraid to do so if I have a child's Apple id, in case I ever have to have an adult I'd. When I created my id, I was a child. So what I want to know is: How can I check to see if have an adult or child Apple ID? I don't know if you will find it helpful to know that when I go into my iPad settings>iCloud>Set Up Family Sharing, it allows me to set up family sharing and DOES NOT tell me that an Adult Family member is required (I don't want to set up family sharing, I just wanted to see if I got that message). So that to me means that I have an adult Apple ID, and my birthday on my account is well old enough to be an adult... So I wrote out my questions in order, thank you all sooooo much for the help!!
