Retirement tax questions

Thank you so much for clarifying that! Indeed, changing my answer to yes for the question, "Did David Inherit the IRA from Vanguard?" makes the distribution taxable. Maybe TurboTax could change the phrasing to, "Is this an inherited IRA, that David has at Vanguard?" since clearly I did not inherit it from Vanguard. Ironically the fact that they customize the message with my name and the institution name makes it a lot harder to Google. Thanks again for the help!
