I was receiving the same Site ID Recaptcha error that many others are reporting, while trying to import 1099s from Pershing BNY into TurboTax TY2024 Windows 11 version here in mid-Feb. 2024. I combined several suggestions from others on this site and got it to work. Simple solution steps as follows: (Note: I am unsure which of these actually fixed it).
1. Update TurboTax (mine already was up to date when I received the error) just to be sure.
2. Update Windows 11 (I installed everything it offered). Windows 11 update is not really great at status communication, so I just kept rebooting and asking it to recheck for updates until finally it showed that all updates were downloaded and installed 100%.
3. Next I logged into my Intuit account on the same computer I was running TurboTax.
4. Then I logged into my bank account (BNY) on the same computer I was running TurboTax.
5. I then went back into TT to import the 1099s, and it worked!
Good luck.
