The amounts in box 1 and bax 3 and 5 should be the same.
A situation when those boxes are different are when you make so much money that you max out what you need to contribute to SS.
No there is a special rule for household employees that if you pay their employment taxes they have to pay income tax on that, but they don't have to pay employment tax on it as well, so the amount of tax you are paying for them is added to box 1 but not box 3 and 5. This is how pub 926 describes it--
"Not withholding the employee's share. If you prefer to pay your employee's social security and Medicare taxes from your own funds, do not withhold them from your employee's wages. The social security and Medicare taxes
you pay to cover your employee's share must be included in the employee's wages for income tax purposes. However, they are not counted as social security and Medicare wages or as federal unemployment (FUTA) wages."
OP, in my experience, state income tax is based on federal income tax so I would put the amount of box 1 on box 16. Also not sure if you are already doing this, but I found the SSA site very helpful because it both electronically files your w-3 and generates a printable PDF of the w-2.
