Chemistry question over resonance structure?

I went through the process of drawing the structure for this ion(sulfite) and somehow the octect rule is satisfied once the remaining pair of electrons is used for the central atom "Sulfur"

1 S atom * 6 valence electrons + 3 O atoms * 6 valence electrons + 2 electrons from the negative charge = 26 valence electrons

26 electrons / 2 electrons/pair = 13 pairs

I drew 3 single bond from the sulfur atom to each oxygen atoms

13 pairs - 3 pairs = 10 pairs

Now i put 3 pairs on each oxygen atoms and now i have my octect for oxygen and im left with one pair of electron and i give it to sulfur and now each atom is satisfied right???

If im wrong please tell me where i went wrong
I was asking because on my chemistry book it shows it has a resonance and on the answer key it looks nothing like mine and most of the times books are supposed be right
