call the broker to see if the .txf file is still available (not the .csv or.xml). I tried to import 2019 data for that return and 2018 data for that return from several brokers. they were not available. since there have been no recent updates to either program, I'm of the opinion it's the brokers that have stopped providing the import data. so there's nothing Turbotax can do.
if your broker says it's available ask them for the link.
