Welcome to the forums Madison.
Glad to hear that you are on your way to begin rebuilding your credit.
I did want to comment on one point you brought up. You asked if you add more money to the card, where does that money go.
You are correct, any additional funds you deposit to Capital One….grrrr….are held with the rest of your initial deposit.
I have tried to ask that all my money I put in be refunded to me, minus the initial $200 I had to deposit. I was told that if I wanted any money back, it was all, and close the account, or none. That is why I refuse to deposit more for a higher CL. I am doing just fine with $500 but wish it was higher.
