Thanks for your detailed response.
How does a pdf file get loaded into an e-file by TT? Was this option available for the 2021 tax year? It would have to be uploaded into TT by the user at some point, I would think, but where? (Perhaps this option will not be available for efiling?)
I don't believe that all brokers offer the option of downloading 1099-B forms. For those who do, I presume that TT is able to transpose them in order to prepare the Form 8949. On the other hand, if there are no wash sale adjustments to be made, I assume that no mailing at all is required? You noted that copies of the 1099-B would have to be mailed in to the IRS, but doesn't it already have this info? (I do not want to snail mail a tax return to the IRS, especially if it exceeds 100 pages!)
Thanks again!
