I've tried multiple times, but I've been unable to have Turbo Tax convert info from my 2019 HR Block 1040SR to Turbotax 2020. Is the issue that I'm now using 1040SR?

I'll go back to HR Block if it isn't designed to work with 1040SR, but the first line in the sales lit. is that it will convert from HR Block.  Decided to try it last year, but want to come back (but won't if they misrepresented its capability...).  I've tried pointing TT2020 to
the HR Block 2019 pdf files...
