State tax filing

I already submitted my federal return through a different website so unfortunately now I cannot submit my state returns on TurboTax since I cannot submit my federal return with out it being denied. The best option seems to be to mail in my state returns.

So I only submit the W2 that has the taxes for that specific state? Even though my gross adjusted income shows the sum of both incomes, I only need to provide the W2 for the state in which I paid taxes not both W2s to match the gross adjusted income? Just a little confused because the directions provided by TurboTax are nonspecific and just say attach the W2(s).
