Cannot get form 1116 to show up. I have foreign taxes paid and non-used tax credits from previous years. Where should I entered foreign taxes paid to generate Form 1116.

If you paid foreign taxes, enter foreign tax credit in the search box at the top of the screen and click the Jump to link.  If you have foreign taxes paid on interest or dividends, then you should enter those foreign taxes in the 1099-Div and 1099-Int sections.
