No the IRS will not send his refund to you. The IRS will only deal with him on his return. Texas child support agency might have an offset in place to keep the refund and then send your child support to you. The IRS never sends someones refund to another person/bank account. How would the IRS know your bank information? As I said earlier, I suspect he got his refund BUT then It was held by the Texas child support agency (it was an offset) to pay your back child support. It is two different things.
So what I am trying to say to you is you need to AMEND 2017 and claim your daughter CORRECTLY and get your own personal refund back. He is claiming your daughter in order to get enough money to pay your child support and that is not right. He is not entitled to claim your daughter. He should pay child support anyway not "steal" your exemption. You need to look at your bank information from last year and see where that deposit came from I do not think it was the IRS. Again the IRS would only send his refund to him, BUT his refund was offset because of his child support debt.
