Solved
There's a blurb at the bottom of the 1099-B Section stating I need to finish reporting my stock sales by mailing in a form. Is this mailed in when I e-file my tax return, or would I need to mail in my 1099-B forms separately?
No you don't mail 1099-B forms. The IRS receives copies of all 1099 Forms. You input the information that is on the form and the correct tax forms and schedules are sent to the IRS when you e-file.
