Do I need to report dividends that show up under the "nontaxable" tab in vanguard?

[mseibel21]

The "taxable" tab is blank, but there's over $1000 in dividends and capital gains distributions on a Roth IRA listed in the "nontaxable" tab. I did not receive a 1099-DIV.

No.  You do not need to report dividends or capital gains from stocks/mutual funds held in an IRA, Roth or Traditional.

[Opus 17]

With any IRA or a Roth IRA, everything that happens within the account has no tax consequences until you withdraw the money. Then, the money you withdraw is either taxable or not taxable, depending on the kind of account and whether you meet all of the rules for making withdrawals.  You don’t keep track of gains or losses or dividends within the account, only the final amount of money that you withdraw  when you withdraw it.
