Error on State form before filing but after filing Federal

[Kori1]

I am using the desktop version, my spouse and I are filing MFS and we're taking the Federal standard deduction. My spouse has filed both his Federal and State return. I had filed my Federal return and found an error with my State return before filing it. To correct my State return, I need to change answers to the TurboTax interview in the Federal deduction section. Basically, I had data entered property tax information and it transferred to my Oregon itemized return but my spouse claimed it on his Oregon itemized return. 

Can I go back into the Federal interview and delete the information I entered for property taxes? I tried duplicating my return to test it but the program continues to lead me towards filing my Federal return - but I don't need/want to. The change won't affect my Federal return, just my State return. Is there a way to make the correction so it updates my State return and any worksheets and comparisons TurboTax prepares without filing the Federal again?

You will probably have to mail your state return, instead of e-filing it.
