Was your spouse's 2023 return filed late in the year such as after October 2024? If so, then an AGI frequently doesn't show up in the IRS database because of the late filing, and an AGI of 0 would be used.
Regardless, if this was happening to me and a spouse, I would try using my 2023 AGI (as taxpayer 1) to verify me, and I'd try using an AGI of 0 for the spouse. Surprisingly, that sometimes works when the IRS database is not matching. It's quick and can't hurt anything to try.
