I've experienced the same frustrating issue.
For now, crypto traders must use the Online platform in order to import information into the program. Someone suggested to me (I don't use the Online platform either) that I could use Online to import the info, then copy the file and use it in the Desktop platform.
I will say, however, that when I entered the crypto sales into my Desktop program, it did generate the Form 8949 you've now been asked to submit. The only difference I know is that I use TT Home & Business (vs. your Premier). Shouldn't make a difference, though.
I'm so sorry for your experience. It has been a frustrating year for me, too. Hopefully, TT will improve the experience for Desktop users and better equalize the platforms.
