State tax filing

also in 2020, for my 2019 llc taxes i used cd software for my pc.  i can not find this the file. tax2019.  i guess i have to create this filing from scratch or any other way to save time?   also, I checked into my online account turbotax and i downloaded the .tax2019 file i see there... i tried to open it with my current TT software 2020, but it won't read or something.  it says, create new llc from scratch pretty much. reply
