I called the FTB directly and gave up waiting after half an hour and lots of annoying announcements, with no indication of how long I would have to wait. The FTB system for returning calls malfunctioned and I didn't get a chance to leave my number. I decided to seek help from GetHuman, just to navigate the FTB automated call handling system more effectively and "get a human". I discovered that they now offer a free calling service that would call the FTB for me and ring me back when it got a person on the line, so I could get on with my day. It took about five hours for the callback to come - probably not the fault of GetHuman - but indeed it happened, and I got my problem with the FTB resolved on that call. At the end of the call, I recommended GetHuman to the FTB agent, who had been pretty confused about getting a call from a robot saying it had to get someone on the line to talk. Fortunately the agent didn't follow the impulse to hang up!
