You do that directly from the main forms. Depending on the tax program used and the diligence of the preparer, you may be able to get the information from supporting statements. If both of you had accounts at the same bank and the preparer simply typed “Wells Fargo” and a dollar amount for each of your accounts, the statement may not help.What I describe in the first paragraph can be a lot of work. The easiest thing to do is to request a transcript from the IRS. All income reported to you is under your Social Security Number so you will see only your income. If there are sales of securities (stocks, bond, mutual funds, etc.) then you would need a copy of the 1099 from the broker which should give your cost basis information.
