My wife has an ITIN, as she is on a VISA that is not eligible for SSN. I have an SSN. The first stimulus rules were that we won't get any payment unless I served in the military (or some other exceptions) if both people filing jointly did not have SSNs. So, we did not get any (correctly). The second stimulus rules were different and we got a payment of 1800 for me and two US citizen children. All of this is correct, but Turbo tax seems to think I should have received a first stimulus and tries to give me a credit when I enter 0 as the first stimulus payment. It does not seem to have the rule put in to calculate the first stimulus eligibility differently if filing jointly and the spouse has an ITIN.
