Same thing just happened to me. I finished my 2019 return and thank goodness had filed it but went back yesterday to make a correction and it is gone. I bought the CD Home & Business version. When I try to open it it askes for my license number and is treating me as if I am signing on to start a new return. I luckily have a PDF copy but how do I make the correction to my return without having to enter everything all over and what is to prevent this from happening again. I have used Turbo Tax for years and never had a problem before. I did try to see if my 2018 is still intact but when I tried to open it it asked to update with a "critical update" which I did not do but also would not let me go beyond this point. What do I do.
