I have been trying to reach a live human being at Turbo Tax, but to no avail. The 800 number is a degrading and useless exercise in frustration. I don't speak to computer voices. I was notified by the IRS that I had overpaid my 2019 federal return substantially. It was filed and checked by TurboTax. Yet, the tax calculation was wildly incorrect resulting in a large overpayment. What is going on? Why didn't TurboTax catch this?
