Unable to download apps on my iPhone due to payment issues

Re: "I cannot download upload anything to my Apple phone it says that all of them have $21 why"

We are all apple users, like yourself, in the community, so no-one here has access to your accounts or details to check the situation out for you. We.d like to help, however.

See Apple Support's online articles (links below) to help troubleshoot:

First, to find out what you were charged for:

See: If you see 'apple.com/bill' on your billing statement - Apple Support

Eg: says:

1. " To see your purchase history, go to reportaproblem.apple.com.
2. Sign in with your Apple Account.
3. A list of purchases appears. To see family members' purchases, select the Apple Account button and choose a family member.
4. To see the full receipt including tax, tap or click the date. Multiple purchases, including subscriptions, might be grouped onto one charge.

If the charge is for a subscription that you no longer want, you can cancel the subscription.

Find out where else you can view your Purchase History."
