I bought Turbotax last November from Fall-Lantern.com. My hard drive crashed,

I bought a copy of Turbotax Premiere Federal and State 2020 last November from from Fall-Lantern online.  I was able to compute and file my taxes this spring with the software.  Unfortunately, my hard drive crashed recently, and I've had to reinstall all my software.  I re-installed Turbotax successfully, but I cannot activate the program with the license code that worked last autumn.
How can I activate my license?  I want to access my 2020 data when the time comes to buy and use the 2021 Turbotax Premiere.
