I am getting an error which is preventing me from filing my federal return using NetFile. The error message is "PPIP earnings were specified on a T4 slip which originates outside Quebec. You are NOT eligible to file the federal return using NetFile. If you are not able to correct the problem(s) shown above you will need to file a printed return." I'm looking for advise on how to correct this as I do not have any PPIP earnings on my T4.
