The problem with TurboTax's handling of the income side is when you enter the 1099-NEC. If you are not going the partnership route, you have to assign it to one or the other taxpayer, and then you can't change it on the Schedule C.
What I did, and what I hope works, is to report TWO 1099-NECs for our community-property-state LLC, each for half the amount shown on the one we received from the Payer, and each of course with the same EIN for the Payer. I assigned one 1099 to myself and one to my wife, and now I can go in and manually split the expenses I had entered on the single Schedule C between the two of us. Fingers crossed.
