If TurboTax is preventing you from even entering the information about the camp, it is because both parents must have earned income. If both of you did have earned income, I would check to make sure the W-2s or other sources of earned income are properly in each spouse's name.
If one spouse did not have earned income, you are still eligible for the child and dependent care credit for the months that spouse was a full-time student or physically unable to care for themself or for the child. Once you answer No to being a student or disabled, TurboTax determines you are not eligible for the credit.
