"So they give you SCH D and and 8949 file""
If that 8949 file is a PDF file, TurboTax Online will ask you for that file when you use the TurboTax Summary option.
The same goes for your other transactions for which you have details ready.
I don't think TurboTax will take multiple PDFs, so you may have to use a PDF editor to combine them into one PDF file.
