I can't even open Turbotax.  When it asks if I want to get the available update there is no option to say "no" (the "no" button is faded out and cannot be used) to go straight into Turbotax.

But did the "fix" work for you?

I uninstalled and downloaded again (the download is the updated version). It still doesn't fix the line 68140 needing to display the sum of line 21 of all T3s. We have a net capital gains loss, and 68140 displays 0.

THIS UPDATE DOES NOT FIX WHAT IS BROKEN

I did the same thing...did a complete reinstall...and T936 still does not populate.   The fix is NOT in. 

The update does not work.   I called TurboTax and was sent a link to reinstall.  Once that was installed, the capital gains split was correct.  I netfiled without error.  I also refiled my spouses return as it was sent earlier with no capital gains since the splitting was not working.  All is good for me now.

WTF? Look at the error message below after trying to reinstall. I've been installing TurboTax updates for many years. Never encountered garbage like this before.

I had to completely uninstall and then reinstall TurboTax from the new build at this location: https://turbotax.intuit.ca/tax/software/download

The About Box is now updated. I have never had to do these extra steps before.

About Box before reinstall:

About Box after reinstall:

I just did a full reinstall (I did not remove it, just reinstalled over it).  It seems to have worked.  When checking for an update manually it says it is up to date.  And lines 17599+17600 on Sch 3 now equal line 68140 on T636.  I split 50-50 with my spouse with capital gain (not loss).  I have not tried to Netfile yet.

Opps typo above ..I meant T936

Can you please share the phone number you used to call turbotax?
