Unable to enter US Government Interest from 1099-DIV

[randmac]

I imported my 1099-DIV from Vanguard which included dividends from several funds which earned a percentage of their income from US Government Obligation. However, when I get to the screen where it asks me to enter the US Government Interest, the box to enter the number is grayed out and it will not let me enter anything in the box. I am using TurboTax downloaded to my MacBook. Anyone know why the box is grayed out and how to get around it?

On a whim, I tried entering the 1099-DIV manually (instead of importing it). When I did that, it let me enter the US Government interest. Workaround discovered.
