I haven't tried this Kipa, but I believe if you go into the Tax Payments Worksheet and input your final payment with the anticipated payment date, it will stop interest calculation at that point. At one intermediate point in my hassle with this I noticed that the incorrect calculation TT was making cut off at the point that I made the 1/15/22 estimated payment for Q42021, which brought my total payment above the miscalculated installment due for Q1.
Also, I believe that the IRS would recompute the interest once it receives your payment and issue a refund of any overpayment. I say "receives" advisedly as I have in the past (not related to me) seen where they might not cash a check for a month or more after they get it, but the interest calculation stopped a couple days after the return was sent in. So I think they flag the correct date received and give credit for payment on that date. (But no guarantees lately given the issues they have.)
Obviously, it's still a bummer to overpay due to a TT error that they won't even acknowledge.
Hey everyone in general following this: I'm not on Twitter but maybe some of you are. Does Intuit or TurboTax have a presence there? Publicly calling them out on this obvious error would really cause them to have to look at it, particularly if the IRS watches their feed.
