A friend called and asked for help with TurboTax 2017 as he was getting error TT400 trying to save a file. He checked and all his TurboTax 2017 files gave the same error. I opened my TurboTax 2017 and it wanted to install an update which I let it do. Now I cannot save any of my TurboTax 2017 files either. It sounds like this latest update is defective.
