My problem importing Fidelity 1099B transactions was resolved. I waited a week since posting and ran Turbotax program which performed system update. I switched to Microsoft Edge browser and made it the default. Cleared out the cache, set security to Basic, turned off Pop up Blocker. There were no ad blockers or other similar apps installed since I don't normally use Edge. I went through normal Turbotax procedure again for importing and this time it worked. I don't know what the issue was but this is what I did. It did not previously import with Firefox or Brave Browsers. Hope the rest of you have the same luck as I did!
