Yes, and correct - when you e-file, you don't have to send in copies of forms. When you file a return by mail, attach a copy of Forms W-2, W-2G, and 2439 to the front of Form 1040. Also, attach Forms 1099-R if tax was withheld. TurboTax will print an instruction sheet that lists what you need to include when mailing your return.
