If you filed as Married Filing Jointly your incomes are combined on the tax return.
You can look at the individual income forms you received for each of you, Form W-2's and Form 1099's
Your Form 1040 combines all of you and your spouse's income--so you cannot see it separately on the tax form. You can check your own W-2's and 1099's and do the math for yourself. You are supposed to save those documents for your own records. Or you can look at the worksheets that are part of the pdf of your tax file and see what was entered for each of you.
