I need to file my 2019 taxes

Im filing 2018 and 2019 taxes that not never got filed. I downloaded 2017, 2018 and 2019 turbo tax software to complete filing my taxes, i already finished the tax return for the 2018. But now i need to do 2019, My question is do i use he same software that i already downloaded or do i need to download it again and pay another 70.00 dollars?

 

When i click on file another return i cant tell if it's showing it to be 2019 tax file or if its just doing another 2018, can you help please.
