I seriously hope turbotax has not been recommending this to anyone.
The CRA states it is considered taxable income, it doesn't state pensionable or insurable income anywhere.
I was finally able to get an answer from the CRA after many days of being transferred between departments and senior agents on this and all CEBA/CERS/CEWS/TWS payments go on line 13000 and specify in that line what the other income is.
