What’s bigger- all the water on Earth collected into a sphere or a neutron star? For perspective, 70% of the Earth is covered by water, but it’s only at the surface. A neutron star has half a million times more mass than the entire Earth.
The answer?
The water would reach across about a third of the United States, from Utah to Kansas:

A neutron star would reach just beyond the five boroughs of New York City:
