Turbo Tax latest updates, as of 3/10/2021 have only made the issue more incorrect. Now overpayments from 2019, applied to 2020 estimated payments , are not being reflected on Form 2210 and therefore, the 7/15/2020 column (a) on Form 2210 Part IV, in my case, now incorrectly reports and underpayment. When will this be corrected?
