TT 2020 or need to buy TT 2021?

Maybe a naïve question: I bought TT business 2020 for my LLC taxes last year. Can I re-use this same software for the 2021 LLC taxes or do I need to download a new TT business 2021?

 

Also, in case I download a new TT 2021, will it be able to pull information from the TT file created and saved on my computer by TT 2020 last year?

 

Thanks!
