I assume you mean AGI (adjusted gross income.) And I'll assume this is a filing status of single, since you didn't say otherwise.
If you used the 2023 AGI from the original 2023 return (not an amended one) Form 1040, Line 11, and if it was rejected, then try to use a 0 (zero) for the 2023 AGI and efile again.
For some reason it's not matching the IRS database. This is more prone to happen if one filed the 2023 return late in the year, but sometimes there's not a known reason.
