I am having the same error.

That fixed it.

@DirkD Thanks for the update. We appreciate it!

Well I did that but it didnt fix the same problem for me.  Any other ideas?

Through trial and error I figured it out.  If the date of disposition is before June 25 2024 then teh data will transfer to sched 3. but if on or after it will not.  June 25th was the date that CRA was going to change the inclusion rate, but in the end the rate didnt change but it was late notice and CRA did not update all forms adn i guess the software looks for this date.  Seems like a glitch in turbo tax.

Yeah, I had to put in the disposition date to get it to work.  There are two different parts to schedule 3 it could put them in based on the date - so maybe TT needs the date to know where to put it.  I didn't have to do this in previous years.

I would hope that TurboTax could make an adjustment to solve this issue.  I just had to manually insert a date of 01/01/2024 for 48 entries on one client.  Downloading T5008s from CRA ends up creating an incredible number of entries....so I am not pleased...

Also, I assume that thousands of TurboTax users will not notice this issue and incorrectly file their returns....

Thank you!  You found the answer - I also had 3 items that would not transfer from the T5008 form to Schedule 3, but changing the date of disposition did the trick.
