Late filing 2018 and cannot seem to import 1099-b from Merrill Lynch. Says that forms aren't available until February..

I'm late filing a 2018 return that only contains investment income for a dependant and I cannot seem to import his 1099-b from Merrill Lynch.  It implies that past years data is not available? is that true?

There are hundreds of lines in his 1099-b that I really don't want to input manually.
