problems downloading to Itunes

I have just downloaded the Audacity 2.1.0 on my laptop which is using Windows 8.1. I can start downloading music from my record player via a USB unit and it plays back no problem but I cannot get it to download into I Tunes which I use as my main music playing system. Can anyone help with how to do this?

Export to some folder of your choice then add that folder to your iTunes Library:
