INABILITY TO RUN MY TURBOTAX APPLICATION

Bought my Turbotax Home and Business Application 2019 Edition since February. Duly downloaded and installed in this Lap Top. I have been using it for a time. At this time today 4/2/2020 I can no longer run it. It has requested the Activation License code many time. It looks like it does not recognize the code that came with the application. What should I do now?
