Get your taxes done using TurboTax
I am having this same issue; I tried importing from several different brokerages, with the same problem across the board. I am using Win10, no VPN, Google Chrome as default browser everything running on latest version. I use standard Windows Security, also with the latest updates. I do not have any other issues with internet or captchas on any other site, except when trying to import in TT Desktop. WTF?!??? Intuit needs to fix this ASAP!!!!!!!!
p.S.: I did have my router set to AdGuard DNS, but switching that setting to auto-DNS did not make any difference, so that cannot be the underlying issue. My router/modem is a Zyxel C3510XZ, in case that matters (which I highly doubt).
