I need to know separate incomes for my wife and I from last year's taxes

You will have to look at your individual W-2's and Form 1099's for that income.

On a tax return filed as Married Filing Jointly all income is combined for one amount.  You can download a PDF of your return and there will be worksheets available which will show the individual income as was entered.

To access your prior year online tax returns sign onto the TurboTax website with the User ID you used to create the account - https://myturbotax.intuit.com/
