I am unable to NETFILE as I received an error Code 2123, telling me that I am past the period to collect for an EI overpayment and that line 450 must be deleted. I cannot override it, or lines 11 or 12. I need to NETFILE as I cannot make the deadline the CRA set for me if I use snail mail or even courier. How can I override this amount?
You will need to go to the left hand side to T-Slips and find your T4E - Once open you can then delete the amount you entered in box 26 -which is the overpayment. Once completed you will continue and everything should automatically have deleted from the other line numbers once you remove the amount in box 26.
