Problems filing NY and NJ state tax

Hi I'm a resident of NJ, working in NY, and NY state tax is deducted from my paycheck. My wife is also a NJ resident and she works in NJ.

I have some problems when filing NY and NJ state tax using TurboTax Premier online. Both of us are NY non-residents. When calculating NY state tax, I already choose my income is from NY and my wife's income is not from NY. Theoretically NY taxable income should only include my income, but from TurboTax online, both my income and my wife's income are included in NY taxable income. How could I fix this?
