The same thing happed to me yesterday 2/26/2021. The error message was "There is a potential issue with the calculation of your Taxable Inherited IRA". Neither my wife or I have an inherited IRA. We both have 1099-R's to input. I went back and checked that the answer to whether any one of them was an inherited IRA was answered no. I also looked at the "Forms in My Return" and none of the 1099-R forms had any inherited boxes checked. Right now I am dead in the water. There was a response in the error message that a correction is expected by 3/5/2021. I will give it to 3/5 then look for other filling alternatives. I have used Turbo Tax for quite a few years and this is the first time there was a catastrophic failure.
