Hi there,
The program may be asking you to complete a "ghost" form from last year's return that transferred over.
Try this:
Go to the "Personal Income" tab of your interview. Select "I'll choose what I work on". Scroll down to the Investment portion, where you'll see the place for 1099-DIV. Click on the "Update" icon beside the 1099-DIV. From there, you should be able to see the 1099-DIV info for your 2020 return. Look for an empty space and delete that empty form.
Please post back if you still have difficulty.
