If you are using the Online version you log into it is ONLY for 2019. Did you start a 2018 return last year before October? Do not enter any 2018 info into online.
If you are not sure you should try to start over and only enter 2019. If you haven't filed, registered or paid you can try to clear and start over

Do you still need to file a 2018 return?
