Hi guys, I'm dumb. Is there anything I can do with $50 on my itunes account?

I have no experience with Apple but months ago I bought a few gift cards because they were on sale…didnt know they were only good in the app store --. I wanted to use them to buy the airpods that my sister wanted. I’m dumb, did no research, found out it doesnt work for that, panicked, googled, saw a post about gifting credit on your account to someone, took one posts advice and added $50 to an apple account I made just for that, I have no use for it. Was lame but whater. Just wanted to see if you can exchange your credits in any way. All this time I never even seen that other apple gift card ><
