First, I am assuming that $14,490 is the total amount of your Social Security receipts and that $12,317 is the taxable amount of the Social Security on your federal return.
This is because no more than 85% of your Social Security can be taxed on the federal level ($12,317 is 85% of $14,490).
IF you are filing a return as an Arizona resident for the full year, then TurboTax automatically deletes any taxable SS entered on the SSA-1099 on the federal return.
If you look at the screen entitled "Adjustments Summary", you will see a subtraction for "Social Security or Railroad Retirement". The number $12,317 is here because that is all the Social Security that was taxed on the federal return (remember that no more than 85% of your Social Security can be taxed on the federal return). So this is the only amount that needs to be subtracted.
Once the $12,317 is subtracted, then there is no Social Security taxed in Arizona (because the other 15% wasn't taxed on the federal either).
