I have the same question...
Turbo tax is being very vague about it.. Looking at forms 8582 there is really no indication what this box 2a would mean.
Another question on the matter was left vaguely answered.

Can we please get a clear answer about the difference between box 1 - Ordinary Income and box 2a - Ordinary Income?
