These days I assume when I see an MFS question, especially with community property involved, that it's from California and has to do with some weird law they have about paying a higher tax if AGI exceeds a million, or something like that.  

But regardless of the reason, in this case the 2019 credit-elect is the husband's separate property and there's no legal reason to put some of it on the wife's return, any more than some of your estimated payments can go on my return.  (Why would you want to do that, other than being a nice guy?  Well, maybe I'm handing you some cash under the table, and you're trying to avoid a refund because you know it will be seized because of those other taxes you owe.)
