Made an interesting discovery.
On the "Review: Errors" screen, click on "Fix" and then "Edit" for the offending T4. Adjust your CPP contributions (Box 16) by 1 cent and click on "Done with T4 Slips", the error disappears!
My CPP contributions were $1,481.58 with the error. I changed that to $1,481.57 and no more error. Actually any value other than the original will fix the error. Out of interest, I entered $9,999,999.00 and Turbo Tax was quite happy.
Incidentally, if you then change Box 16 back to the original value then the error will reappear.
I really don't think CRA will care if your entered value is off by a penny.
OK Intuit, that should be enough info for your coders to figure out the problem. You're welcome.
