Can I claim 2 out of my 4 dependents, but only take the EIC for one of them? Girlfriend (same house, she makes more) claimed the other 2 kids, but got the EIC for 3/4.

Girlfriend filed first, claimed 2 oldest as dependents and 2 youngest as non dependents; she automatically got the EIC for 3 oldest (the limit, from my understanding). Her return was accepted. I claimed the youngest 2 as dependents and older 2 as nondependents, and from my understanding, it automatically tried to do the 3 for the EIC for myself, as well, and mine was rejected. Can I, and if so, how on Turbo Tax do I claim the youngest two as dependents while only taking the EIC for the one child she didn’t? I can’t figure out how to manually do that.
