The computer is up-to-date. Even though it is not, it should not cause such a problem. Ad blockers should not cause such a problem. No one should disable their Malicious Content Filters or Intrusion Prevention systems, disable security settings in the routers, basically strip all their network security to "please" turbotax with faulty code failing to connect to the partner databases. Simply a bad implementation with no enough testing to sell the product quickly, and yeah when the users are tied with the purchase then they can fix the bugs. This is not the first time, last a few years turbotax was operating in this mode, selling buggy software then fixing bugs all the way till end of tax season! I remember for 2022 tax year they had a faulty import of Robinhood sales which they didn't even announce. After I filed the taxes on mid-march, I happened to open the Turbotax desktop app sometime in April and got a message that they screwed up with Robinhood import and I had to add an ammendment to my tax report with the fixed values.
