Saw this post :
On MacBook Pro with MacOS Monterey 12.0.1 I was unable to connect to Intuit server for updates to Turbotax. My new install of Turbotax 2021 failed with an error of inability to connect.
Solution: performed OS update (to 12.1) and rebooted twice
THEN (and this may be the only required step) - rebooted in SAFE mode (hold down left Shift key immediate after hitting power). That cleans out caches and thereafter Turbotax runs normally with easy updates.
