I'm glad that resolved it, and that you could complete the import. I haven't seen anyone ask before about a problem with 2-factor authentication with that log-in interface from desktop TurboTax to import from ItsDeductible.
I'll ask fellow SuperUser @ SteamTrain to comment here if he has seen any posts about 2-factor authentication being a problem with that import process. Maybe it doesn't need the second factor in this case so didn't send one. But in any case, it sounds like you were able to finally complete the process.
