i don't think any version of Turbo Tax allows for an attachment of a PDF if you e-flre - only if you mail in the return. the reason is that that pdf has to be converted to a binary format to be transmitted. since every broker is a little different there's no way TT can do this. so your options are to mail your return with form 1099-B attached or use form 8453 and attach the 1099-B. make sure totals for various lines on form 8949/ schedule D agree with sections on the 1099-B. also, read the filing requirements for the 8453
