Two days agoTabatha (from Turbo) helped me correct the double entries of data for the T5s and T3s that was the problem. After entering new data (corrections) to the T5s and T3s I sent the this to CRA via regular mail, as instructed, in the form of new pages for the "T1 General Condensed 2019".
I now await the reply from CRA and confirmation that the correction has been understood and accepted.
