Can not Add Supporting Details. When I right click in box do not get supporting details option. Click on Edit and Add Supporting Details is grayed out.

Can you please clarify in which section of the program you are having this issue?

Where are you trying to add supporting details, and what are you trying to add?

Thanks for your help. I was working on 1099-DIV  under 'A protion of these dividends is U.S. Government interest.' Next is where you enter the ' US Govn't interest - and I wanted to add supporting details about each funds portions. I found that if I went to EDIT and clicked 'Add Supporting Details,' that worked now.

Thanks.
