Yes, if you are filing a joint return with your wife and your adult daughter is on your policy and is not claimed as a dependent on your return, then it is one of the appropriate ways to allocate each of the boxes based on having 3 people on the policy. The numbers need to add up to 100% so, you may want to give your wife and you 67% and your daughter 33%.
If you believed you were going to claim her when the policy year started, then Situation 4 would apply as well. This allows those who believed that someone would be part of their tax family to agree to the allocation amount instead of allocating it based on the number of people on the policy. In this situation you can allocate anywhere from 0%-100% on your return and your daughter can do the same as long as the numbers add up to 100%.
Additionally, since your daughter is no longer in your tax family, you should update the Marketplace with that information and she should get her own policy. It is best if each tax family has their own policy since the credits are based on your tax family household income.
