Can I itemize deductions on a WI Form 1 State Income Tax return even though I used a standard deduction on Federal form 1040?

I filed with Turbo Tax and claimed a standard deduction for Federal.  There was no schedule A prepared or filed.  Therefore, the state return did not populate and file itemized deductions on my WI State Return (Form 1).  I filed it before I caught the error.  I want to file an amended WI Form 1 with itemized deductions.  The form refers to the Federal Schedule A to claim deductions for State.  Can I itemize deductions on the amended state return even though I did not file a schedule A for Federal?
