T5 Filing error

Hi everyone, I’ve downloaded the XML file from tax cycle and try to submit using WAC, this is the error message:

Error: We are unable to process your submission because the transmitter CRA account number given in the attached T619 electronic transmittal record does not match the account number you used to sign in.

How do I fix that?

Thank you

Make sure the transmitter number entered on the Engagement worksheet matches the transmitter number used to sign in and transmit the return, as the CRA will validate the T619 transmitter information in the XML file to ensure it matches the sign-in information.
