You haven't said whether your husband is the only member of the PLLC, or there are other members. If he is the only member, you have to enter the PLLC in TurboTax as a business. You report the money that the agency paid to the PLLC as business income.
It's the "pays himself through his PLLC" that's the problem. He can't do that. The income that the PLLC receives from the agency is your husband's personal income because, as I said earlier, "your husband and the PLLC are one and the same." He cannot give himself a W-2. He needs to talk to his accountant about how to handle his income. Again, this is all assuming that your husband is the only member of the PLLC.
