Within Schwab you may have to go into Security settings, then to Linked Apps and remove prior connections to Schwab. Open TurboTax and delete any 1099 connections to Schwab, then restart application. I had to do that to clear any old cache. Restart TurboTax and make connection and Import. May have to do a few times to see if Import worked.
Also there should be data in PDF, XML and CVS. If not, in my case I had to contact Schwab support to re-load new files.
