Always a trade-off between keeping it simple and getting into more extensive and
complicated procedures.

In this case you need to blur just the shadow area. Working on that layer, make
a selection around the shadow somehow. You can use the free select tool and
carefully draw around it. Another way is use what is called the quick mask and
paint the selection in.

Use Select -> Toggle Quick Mask (down the bottom of the menu) That gets you a
red cast over the image. Painting in White makes a selection, painting in Black
removes a selection. So using White fore-ground colour and a suitable sized
brush, carefully paint over the shadow.

Now go Select -> Toggle Quick Mask again (to toggle off) and you get those
"marching ants" denoting the selection.

Use Filters -> Blur -> Gaussian blur with value 30 to 40 and apply that :

Turn the selection off Select -> None gives this:
