This will not affect your return. TurboTax is just alerting you that your SDI (California state disability insurance tax withheld and VPDI is voluntary plan disability insurance tax withheld) is more than the maximum amount allowed. The maximum that should have been withheld is $1,539.58. You need to reduce the amount entered on your W-2 to comply with the $1,539.58 total. Talk to your employer if you want to have the excess refunded to you.
