State tax filing

@MaryK4  Thank you for the reassurance!

 

So if I'm applying $154 of my IRA deduction (filing jointly, and my full federal IRA deduction is the entire $12,000) to my CA state taxes, this essentially "cancels out" my small amount of Nonresident CA income (zeroing out my CA tax obligation)?

 

Should I be making sure to subtract this from the amount of the IRA deduction I take on my NY return? (i.e. NY IRA deduction should be $11,846 as opposed to $12,000)
