Well, as usual, I figured it out myself. In case anyone else runs into this, this is how it's done (remember, this is for the desktop version of Turbotax Premier):
- Click on the "Wages and Income" Tab
- Scroll down to Investment Income
- Click Update to the right of "Stocks, Mutual Funds, Other
- Edit the investment account (1099-B) containing the sale entry
- Click continue on change account number screen
- Scroll down to the sale of the inherited stock and click edit to the right of it
- Where it says Box 1b Date Acquired, simply overtype the erroneous date with the word "Inherited"
This does not require an override, Turbotax will allow you to simply enter Inherited into the date box!
