I'm having the same issue (same message and 103 code).
Tried to select Webull Financial and Apex Clearing and didn't work.
Btw good suggestion from @CA38 , thanks, for one second, think the issue was solved.
I am using Premier on the Website.
I can't find anything in my webull account related to "Enable Third-Party Access."
Please, can anyone from Turbo Tax have any suggestions?
