You're requesting the volume to shrink by 11GB, yet you only have about 6GB unallocated.
You can more efficiently use allocated extents by rebalancing the volume. Executing a command similar to btrfs balance start /home
will start that process, and it may take some time to complete.
But I don't know if that will free up enough for a large amount of shrinkage.
I though I add14.31GiB
free according to this :Free (estimated): 17.29GiB (min: 14.31GiB)

But you're requesting a volume change, which deals with allocated extents rather than how they're used. You could have almost the entire volume "free", but if the whole thing is "allocated" you can't shrink it. Running a rebalance will reallocate used data in a more efficient way.
