I am in a quandary here.  In completing my 2023 taxes, somehow , an amount of $14,859 shows up as employment income on the federal T1 form. 

I am  retired and I have no idea where this amount comes from.

I  double clicked the amount on T1 to find out where the the source entry is so I could delete it. There IS NO source entry for this in the Federal t4 slip boxes ( nor ANYWHERE else that I could find. 

Where can I find where this amount comes from. 

I really don't want to over ride it because I am afraid that net filing will be disallowed. 
PLEASE HELP 

Thanks

Rob
