I talked with a TurboTax customer service specialist. I shared my screen and she acknowledged that I could not import. She said that she would log the issue. I confirmed with Ameritrade that the document number was correct and that the document number does not need to have alpha characters. I had mentioned to Ameritrade that my current ID number only had numeric characters but for the TurboTax website, the example of a document ID number included both Alpha and numeric characters.
