Double click on the dividend line and go to the supplemental dividend worksheet. There is a line to enter that I just did one

Oops. I wrote 1099-DIV instead of 1099-INT. when I go into the interest income worksheet, I cannot find any place to enter the Box 11 information..

PATAX answer still applies    For interest or dividends..... double click the payer line to open an additional information worksheet

I didn't see a box/line specifically for Box 11
