Troubleshooting

That's precisely what the Tier 2 agent told the Tier 1 agent, as claimed, yes:

TuboTax Online no longer exports the 3-pages of the CNIL to your downloaded PDF return, as it did the past decade I used TurboTax Online. But the Tier 2 agent claimed the NETFILE will be correct when it's submitted.

In my case I was just entering "Investment Expenses" (in the black TurboTax sidebar) as a Carrying Cost. That Carrying Cost appears at the back of my PDF in the Deductions pages, and in line 22100 at the front of the PDF in the T1. But the 3-page CNIL which also has line 22100 - is completely missing in the downloaded return PDF from TurboTax Online.

I plan to NETFILE tomorrow, based on the moderator's comments, and the Tier 2 agent. I'll just be missing the CNIL this year in my downloaded return.
