When importing one of the steps required was to log into intuit account. While logged into intuit.com I have a menu bar on the left. One is called Documents and that is where I see all my schwab tax files I downloaded but were not imported.

However, after reading other posts I finally fixed my import problem. I had to disable "Brave Shields" for the popup browser. After disabling the security I was able to import. I know I did not have to do that last year.
