My email address is wrong on my Apple ID. When I try to put in my email- it says that address won’t work and I need to pick another one. I don’t have another one.

Have you logged into your Apple ID to see if the address shows under Reachable At, as a Rescue email address, or as a Notification email address? If it is listed, you can remove/replace the email address.

Apple hasn’t published any guidance for using an address again. Normally, if your e-mail address was associated with an ID in any way, for example as a Notification email address or a Rescue e-mail address, then it can't be reused as an  Apple ID email address for approximately one year. I have also seen posts that stated Apple told them there was a 30 day waiting period before the address could be used again. You will need to get another e-mail address from somewhere like AOL or Yahoo to use as your Apple ID or you can try waiting 30 days to see if that works.

You might be able to use your mobile phone number instead of an email address. This article will show you how: Use your mobile phone number as your Apple ID - Apple Support.
