I don't really have many if any deductions at all on Form D-400 so I would take the standard deduction. As a test, I changed one of my North Carolina W2Gs to an $800,000 gross winnings, $800,000 State Winnings, and only $20 State income tax withheld. Then I add $800,000 to the Nonresident Income Allocations form under Other Income/Loss Excluding Sec 457 and Nonqualified Plans - North Carolina Income While Nonresident. All this does is increase my North Carolina refund by $20, making it still give a full refund even if I had an additional $800,000 win in North Carolina. This does increase the Federal taxes due by over $270,000 though.
I have gone over everything many times but there doesn't seem to be any errors. I can't tell what TurboTax is trying to do on the tax forms unless I pay to file it beforehand.
