The fixes prescribed on the Intuit web page (quoted by several people above) were worthless for me (and apparently many other folks as well). I had already spent hours doing my return; but when I went to file it the next morning, I got a 70001 error and was basically stuck. After two calls with tech support, I was no better off. The ONLY thing that enabled me to get my return filed was installing TurboTax on another machine and copying my tax file over to that machine. That machine doesn't belong to me, so it's a temporary band-aid because I have to delete it from that machine and I still can't use it on my machine. This is something tech support never bothered to suggest; maybe it will work for you. Next year, I'm switching to another software package after decades of using TurboTax. This is insane.
