Hi again! Sorry if this is a bother, just wondering if someone might know something about this or not

Hello! I did some side hustle last year and received crypto in payment, which i proceeded to sell in multiple transactions (through Wealthsimple, so i got those records). Now, I did not ask for any kind of documentation regarding the work I did, nor did I produce any kind of receipts about them neither. So, how should I report this? Should I just enter the transaction lines as Capital Gain/Losses? Should I report that through the Self-Employment Business section, should I do both...? The total amount in CAD that I received for the crypto was around 18K Thanks!
