You have not mentioned whether you are in a community property state. It gets complicated in those states--you have to split it all 50-50.
AZ, CA, ID, LA, NV, NM, TX, WA, WI
If you are not in a community property state then you split up the deductions in whatever way the two of you agree upon if you are itemizing. You just cannot double dip or claim more than a grand total of 100% of the deduction. If you file MFS--you both have to itemize --- even if itemizing is a disadvantage to one of you----or both have to use standard deduction.
If you are not in a community property state each of you only puts your own income, etc. on your return.
