The T4 numbers are entered correctly yet still get the error as below

[CalvinW]

CPP/QPP contributions or pensionable earnings have been entered incorrectly. Check the amounts entered on your T4; particularly boxes 10, 14, 16, 16A, 17, 17A, 26, and 28. If the information entered matches your slips, please contact TurboTax support at https://support.turbotax.intuit.ca/contact/

Is it an error or is it a warning? Warnings are just there to have you double check things. If the warning doesn't apply to you, or you are sure you have the right information entered, then it's ok to ignore them.

what if it's not a warning, but actually shows as an error? 
There wasn't a problem, until I did a Turbo Tax update two days ago.
