TurboTax is recommending I make estimated tax payments in 2018. When I decline this, it then asks "Are you SURE you do not want to prepare estimated taxes for 2018?" and tells me that my tax situation suggests that I should and if I do not, I may owe an underpayment penalty.
However, TurboTax has also calculated that I am due a federal refund. Why would I need to pay estimated taxes in 2018, if I've actually overpaid in 2017? What is the logic?
