Received Crypto Reward , sold them last year. Question on how to enter that in Turbo Tax

Received some free crypto after doing some Coinbase learning in 2021. Reported them as Misc Income the same year. Sold the crypto last year. I am using Cost basis as the income that was reported for that year. 

Little confused on the section, how did you receive the investment. Should it be purchased or received as gift? Second option changes the Cost basis to previous owners cost-basis. Which is not correct (I think). Any help will be appreciated
