It looks like now that I have several 1099-R forms with Copy B required to be attached to my tax form, I will have to mail in a paper, and not use e-file. Looking at IRS form it says "Authorized IRS e-file Providers are prohibited from submitting electronic returns to the IRS prior to the receipt of all Forms W-2, W-2G, and 1099-R from the taxpayer." Unfortunately, Turbo Tax does not have an attachment or upload option for Copy B of 1099-R.
