They ask you for your 2015 federal tax return information if you enter your state income tax return (1099-g). You hit continue and it asks you to verify your 2015 tax return information to see if the income tax refund you received can be taxable for 2016. HOWEVER IT ONLY ALLOWS YOU TO ENTER ONE 2015 FEDERAL TAX RETURN not both ! SO you get punished for entering both state income tax refund (single since we weren't married yet), but it only allows for credit for one 2015 return!!!
