"Add to Collection" option missing upon Import

I have a new computer and had to install my Creative Cloud apps.  All's fine exept in LR when I used to import an image there was an "Add to Collection" option on the rightmost panel.  Your Collections would show and you could put a check mark in the box next to the Collection you wanted to add it to.  I don't see it now.  Does anybody know where it went?  Thanks!
