I transferred money from my cash app to my Apple ID I have $8 credit. I want it back on my debit

If I understand this correctly you have money you transferred to your Apple Account balance and now want to have the remaining $8 returned to your cash app.

Normally once funds are in Apple Account balance the only way to get them out again is to spend them.
