Here's how I would do it.

#"K"_3"PO"_3# is an ionic compound.

It consists of #"K"^"+"# ions and #"PO"_3^"3-"# ions.

The #"K"^"+"# ion is consists of a single atom, so it has no VSEPR shape.

Then you draw the Lewis structure of the #"PO"_3^"3-"# ion in the usual way.

You have #"5 + 3×6 +3 = 26"# electrons to place around the atoms to give each an octet.

This gives a Lewis structure of

Lewis structure

The structure has four electron domains, so its electron geometry is tetrahedral and its molecular geometry is trigonal pyramidal.
