A goal I set is a state of the world I am actively trying to bring about, whereas a value is something which . . . has value to me. The things I value dictate which world states I prefer, but for either lack of resources or conflict, I only pursue the world states resulting from a subset of my values.

So not everything I value ends up being a goal. This includes terminal goals. For instance, I think that it is true that I terminally value being a talented artist - greatly skilled in creative expression - being so would make me happy in and of itself, but it's not a goal of mine because I can't prioritise it with the resources I have. Values like eliminating suffering and misery are ones which matter to me more, and get translated into corresponding goals to change the world via action.

I haven't seen a definition provided, but if I had to provide one for 'terminal goal' it would be that it's a goal whose attainment constitutes fulfilment of a terminal value. Possessing money is rarely a terminal value, and so accruing money isn't a terminal goal, even if it is intermediary to achieving a world state desired for its own sake. Accomplishing the goal of having all the hungry people fed is the world state which lines up with the value of no suffering, hence it's terminal. They're close, but not quite same thing.

I think it makes sense to possibly not work with terminal goals on a motivational/decision making level, but it doesn't seem possible (or at least likely) that someone wouldn't have terminal values, in the sense of not having states of the world which they prefer over others. [These world-state-preferences might not be completely stable or consistent, but if you prefer the world be one way than another, that's a value.]
