Are you using TurboTax? This TurboTax support community is run by Intuit, the company that makes TurboTax, to help its customers use TurboTax to prepare their tax returns.
If you are using TurboTax you should not be filling out Form 8949 or Schedule D yourself. Enter your investment sales using the TurboTax interview, and TurboTax will make the appropriate entries on the forms for you. When you enter a wash sale, check the box that says "I have other boxes on my 1099-B to enter." It will then give you a place to enter the wash sale loss from the 1099-B.
