I bought TurboTax Home & Business 2021 for Windows. It worked fine, and I completed my return using my free state of Michigan as one free state is included in the price. I did my son's taxes, and since he moved to Kentucky last year, I bought KY to complete his taxes. After I e-filed his Federal return, he asked me to change a number on his Kentucky return. I launched TurboTax, and it started running one of its updates. The update failed, and after restarting my PC, I could not open TurboTax - I got download error 1603. I uninstalled and reinstalled TT, but it will not load any states now. I contacted the help-line twice and they tried to help, but it did not work. They sent me 2 download links: one for the main program and one for KY. A tech worked with me today and sent me a download link for MI. I've uninstalled and reinstalled numerous times, and I cannot get KY or MI to load into TT. I started a fresh return, and when I get to the state taxes, neither will load. My apologies for the wall of text, but can anyone help me with this, please?
