I've got the refund for X amount for 2018 year few months ago. Now they sent me the letter that I owe them (Notice of State Income Tax Due) for the same amount X, for 2018 as well. So in the end the balance should be 0... I've recalculated this several times, based on everything I earned by my W2 and other sources, and I see the same refund X that state owes me (same number as TurboTax shows)
Also they haven't sent me any explanations or number, why I "owe" them this amount....
