After getting that "locked out" msg from the software - over and over again, I managed to change my Turbo tax password. When the option to return to my 2017 taxes came up, I crossed my fingers, clicked here and there and somehow reached the final screens. Seriously, for hours, it was like navigating a mine field. I have no idea how I finally pushed the right buttons to process the daggone return...but it's now pending on the IRS site. Try signing back in with a new password. Good luck!
