In this case, only one of you would be able to claim your child on his/her tax return. Since the program is unaware that the other person is listing the child on his/her return during the interview, it is calculating EIC for both of you. The other parent shouldn't list the child at all on his/her return because dependents can only be claimed by one person according to the IRS and if you both try to e-file your returns with the child listed on both, then 1 return would be rejected.
