It sounds like you had your backups through iTunes on your computer encrypted. Once these are set, they can be reset but won't help with older backups.
Prior to backing up in iTunes deselect "encrypt backups". This is for future purposes and will not help you with using the current backup. Unless you can remember that encrypted backup, you won't be able to use those.
If you can’t remember the password for your encrypted backup - Apple Support
