The following message appears on the "Automatically fill in part of your return screen."
Will it be possible this year to use the CRA auto-fill function?

"Auto-fill my return will be available on February 19, 2024 from the CRA. Come back to this page any time after that date to import your tax slips."

Also, When I log into TurboTax, I'm told that I'm using the Deluxe version, which doesn't appear in the drop-down list below.

Not sure what is going on with your product this year - it doesn't inspire confidence.
