I literally got a, "This isn't the right form. Next" type response...
Unfortunately, glaring angrily in annoyance at the staff and not saying a word until they extended even an ounce of courtesy by getting the right form for me, was the only way to get through the bureaucratic BS in this situation.
A lot of DMV workers, for reasons beyond me, have a sort of "Oh, you forgot to dot one 'i' on this 300 page form. Go back to the drawing board, get in line again, and see me when you are done" type of attitude. Sure, they don't have the time to walk every single person through filling out forms, but a lot of times this lack of enthusiasm to help at all is pushed to an extreme.
The DMV here has a very strong "You need US more than we need you" attitude to it.
It's one of the reasons I've spent more time driving on expired licenses or with expired car registration than I would care to admit. "Oh, $50 fine? Eh.. Beats waiting in line for the DMV and hating my life for a couple days afterwards."
