Just FYI, for anyone having this similar issue. I spoke with a technical representative at Intuit at [phone number removed] and she tried to solve the issue by updating my Windows PC with all the latest updates/drivers, and manually installing the latest Turbotax software. Unfortunately, that did not help with the corrupt file issue. I am able to open a separate .tax2020 file that I filed for my son's first tax form filing. However, when I attempt to open my file, appears to me the file is corrupt in some way that Turbotax is unable to open. I did ask the support person for any utility that would be able to correct or repair the file but unfortunately no tool was made available. No further support provided. I will need to re-enter all my information, and will take me about 3-hours if all goes well :(
