How can I find my E-Trade 1099-B? I received a letter from the IRS that it was under-reported but I can't see it at all when I go to my 2018 return. I know I entered it.

The IRS letter had the amounts that I reported, and then amounts that they received. Seeing as they have the amounts I entered it must be in turbo-tax somewhere. However when I go to my 2018 return I don't see it at all.
