I amended my 2017 AZ State Tax return (Form 140 on Line 31 to use the Standard Deduction of 10, 336 in lieu of the Lower Itemized of 7,911 that was originally submitted) and when I printed the amendment it printed a amended Federal and AZ State Tax Return, but there was no impact to the Federal Tax Return. Do I need to send the amended Federal Tax return to the IRS, or just the Amended AZ State Tax return? Also, does the Amended Federal need to be included with the AZ State Tax Return? The printed instructions did not clarify.

Thank you for your help.
