I paid 2018 estimated taxes on time in four equal installments which equaled 100% of my 2017 total tax. TurboTax (Windows) generated a Form 2210 "Underpayment of Estimated Tax by Individuals, Estates, and Trusts". I e-filed and my return was rejected because of failure to complete a "Waiver Explanation Statement". Why was Form 2210 created by TurboTax in the first place since I did not underpay my estimated tax?
