I have the same problem with my Federal return. The final page of my Federal Tax Review (when I click on the "Why do I owe $$$?" button) shows that I'm being taxed at a "blended tax rate" of 27.5%. When I do the calculations myself on our earnings ($140,000 filing jointly) using 2019 tax rates, I find that we owe 17,257.68. But TurboTax is saying that we owe $31,706. You guys need to recheck your system.
