I am getting this same error message ... I am using a mac, and have deleted the keychain entries when I had that problem at first where I would never be prompted for my login information from its deductible. Now I can get past that, and keep getting this error: "The operation couldn’t be completed. (com.intuit.turbotax.tpskit.errordomain error 6.)". I don't have a VPN, but I am using an eero mesh router, w/ security features turned on. I turned them off, tried again, but still had no luck ... Why would I be able to successfully download something from a bank institution, but not from its deductible?
It would figure, that this year I have a lot of information that I have added that would need to import and now there are problems - please give me some other solutions if you have them. Thanks.
