How to get a proof of income statement from Social Security?

I need to get a proof of income statement from Social Security for our lawyer. I can probably get my mom to do it, but those phone-robot-menus are hard for her to navigate. I tried to do it myself but the phone-robot freaked me out when it said "anyone who tries to make a false representation to obtain information may be punishable by a fine." I don't want someone knocking at my door saying I committed a federal crime and I don't know if they're recording my voice! I don't have access to their SSA accounts... Has anyone requested something for their parents using the Social Security phone-robot-menu?
