I work with an iMac OSX 10.13.2 Sierra

I have iTunes 12.7.3.46

I am TRYING to put music from a USB stick into iTunes but it goes into the wrong place and I cannot move it once it is there. I have looked at iTunes Preferences>Advanced - but this doesn't help. I have also looked at iTunes.>Files>Add to Library - which it does but it puts the album in the wrong place and I cannot move it to where I want it.

I have successfully transferred two other albums today but this third one doesn't want to go where I want it.

Sorry if this isn't very clear but I am very confused!
