she has no seperate AGI It is combined with mine to make a joint AGI. Only one 1040
On a Joint return there is only 1 AGI number. Use the same number for each of you. So enter the same AGI for her.
If you filed your 2023 federal tax return as Married Filing Jointly, then the Form 1040 Line 11 AGI for 2023 is the same for the both of you.
