How/Where to report wash sale loss disallowed that is on the supplemental form?

On the screen where you enter your stock sales, you need to click on the box that says I have other boxes on my Form 1099-B to enter. Then you will see box 1(g) where you can enter your wash sale losses disallowed.

Thanks for the detailed response. Unfortunately, my investment bank did not report on the 1099 form the cost basis and the disallowed loss. They provided that information on the supplemental form. I was able to go directly into the form and make the input there. Is that an acceptable approach using Turbo Tax?
