I was just helped by TurboTax Business Support (Thank you Emely), and got my qb desktop company file uploaded to TT Biz 2021
TLDR; TURN OFF FIREWALLS AND ANTIVIRUS.
My Setup:
QB desktop pro 2019
TTax Biz 2021
Windows 11 Home
Steps they provided:
1) From a fresh boot up; turn off all firewalls and antivirus (exp. windows defender/windows security settings)
2) Right click on home screen to "refresh"
3) Restart computer, on boot up; ensure all firewalls and antivirus are/remain OFF
4) Open QB and have it on standby
5) Open TTax and go through the 'import company file' prompt
6) ^Hopefully you'll see the company file starting to import
7) Turn your firewalls and antivirus back ON
Hope this helps!
