To input your 1099-Div, please take the following steps:
Continue your return by click My TurboTax > Tax Timeline > Take me to my return

Click Topic Search
Type in 1099-Div and click Go.
To bypass questions regarding a control number you will need to choose the option to 'type it in myself'. The control number is not required to file a tax return only to import. (screenshot attached)
