No, the two are unrelated. If you received dividends after your RSUs vested, then those dividends get reported in the Interest and Dividends section of TurboTax. To access Interest and Dividends,
@GeorgeM777 Why did the brokerage firm report them on on a 1099-B rather than a 1099-DIV form?
The 1099-B is a consolidated statement, meaning it will include more than one type of income. Thus, 1099-Bs will include short-term and long-term capital gains, interest income, dividend income, income from real estate investment companies, and any other type of income paid to an investor through the brokerage firm. Generally, brokerage firms prefer to have one type of form, in this case a consolidated form, rather than multiple separate forms for specific types of income.
