@rjs no, there was no prompting for print after submission. 

@fanfare well, that file was transaction details and turbotax asked me to upload 1098-B which isn't existing since the transactions weren't reported. That said what I uploaded was the datils in form 8949. It seemed like turbotax didnt have any problem with it.

I just want to know if TurboTax has sent that file to IRS or if I need to print and send it again. Its about 250 pages, and unless TurboTax hasn't sent it I dont want to waist that much paper. look here for what I have followed to report those transactions https://www.form8949.com/tto-e-file-attach-work-around.html

@fanfare  Son of a gun. That seems to work. It's news to me. But it's only in TurboTax Online. In the CD/Download TurboTax software, when you get to the sales totals screen it just gives you mailing instructions. There is no option to upload a PDF.

Well that explains why some filers get to upload a PDF and some don't.

Bizarre.

Also, using a third party and paying a fee and entering bogus sales lines is unnecessary, if you have any skill with EXCEL, you can put your own .csv data file into the form and manner of Form 8949 and attach that.

Put your name SSN and tax year at the top of the file.

Or mail it if you use CD/download.

Yeah, that's what I did 😀 But then I couln't see the attachment and thought that turbotax may have had a bug in it.

From this communication, its my understanding that turbotax online does not include the attachments in the view/print but sends them to IRS

Did you ever figured out if TurboTax Online did included the attachment? I did the same thing for 2022 and when I open the return it's not showing the extra attachment that I included.   

I am also wondering about this. It's not in the pdf of my returns, but says there is an attachment. 

If you're using TurboTax Online and downloaded a PDF file of your 1099-B transactions, you are correct that it's not in the PDF of your return.

However, you can add the PDF of your 1099-B transactions to your printed copy of your return (and save both PDF's together on your computer).
