Ok so if you are running on VirtualBox, then your AWS login credentials are irrelevant for a local VM.
On firstboot (from the OVA; or after first reboot of an ISO install), of your TurnKey VM on VirtualBox, you will need to complete a series of config questions. The first question will be to set a 'root' password. This root password is what you will need to use when logging in with WinSCP (or SSH, or Webmin, etc).
Please note that by default, TurnKey Linux expects a US-International keyboard. If you are using a different keyboard, then be sure to not use any special characters (you can configure your keyboard after first login and reset your root password then if you wish).
If you can log in as root within the VM window, but not via WinSCP, then my guess is that your keyboard is not US-International. I suggest that within the the VM window, you configure your keyboard before going any further. You can do that within Confconsole. It's within the Region Config section. Once you've done that, reset the root password like this:
You need to use the root password set on firstboot
