I have reduced the root logical volume to free up 20G in the volume group and would like to shrink the volume group by that amount.  Thanks in advance for your help.

I assume your NT partition is the first partition? If so that means
you need to shrink for Fedora partition from the front which is much
more difficult. To add another wrinkle, your /boot partition and
possible your swap partition probably sit between your NT partition
and the LVM partition.

If that's the case I would backup whatever personal/important data
from the F14 install and remove all the linux partitions. Then you can
use something like a gparted live CD to resize your NT partition (back
up data from it too first just in case!) and then reinstall F14.
