Since the long term capital loss carryover is from non AZ sources, you can't use it to offset your AZ capital gains.
All of your capital gains/losses will be entered on a worksheet for AZ. You get to this worksheet during the Arizona interview by answering "Yes" to the question "Any Other Subtraction Adjustments?" and then answering "No" to "Other Subtraction Adjustments".
On the screen titled "Net Long-Term Capital Gains", you will see the capital gains worksheet shown below. On this worksheet, there are 4 columns. Column a is calculated based on entries on your federal return. For any calculated value in column a, enter the amount that applies to AZ in column b. Then, in column c, enter the amount from column b that was from assets acquired before January 1, 2012 and in column d, enter the amount from column b that was from assets acquired on or after this date.
