This is what Turbo Tax states............If you are e-filing your tax return, you will need to attach a PDF copy of your 1099-B or broker statement(s) when you transmit your return. We will guide you through this process at that time......................
Last year I was able to attach 2 pdfs , signature and details for form 8949 ( 1099 B ). I don't recall how I did it but I am guessing I followed some kind of prompts..... They said they will guide you , but I cannot find any such guidance for the 1099 B. The attachment drop down shows it can have additional pdfs, so there appears to be a issue on inserting more than one.
