If you are using the desktop version of TurboTax (CD/download), then your Deluxe can handle all the forms that Premier can handle. You will not need to upgrade to report any capital gains distributions shown on your 1099-DIV. Your Deluxe Edition should be fine.
It is Online TurboTax where there are some form limitations. Online Deluxe (i.e., website version) cannot prepare a Schedule D for capital gains/losses from sales of stocks/bonds/mutual funds. But even Online Deluxe can handle capital gains distributions reported on a 1099-DIV, Box 2a. So even if you were using Online TurboTax, you would not have to upgrade from Deluxe to Premier solely for capital gains distributions on a 1099-DIV.
