How can I get "Recovery Rebate Credit" for covid-stimulus $600 check 2020?

In 2019 I'm a NRA, but in 2020 I am a resident, and I am supposed to receive the covid stimulus check, while we still haven't filed tax for 2020 so I didn't receive the 600 check. I found in the irs website it said in this case I can get recovery rebate credit in my 2020 tax filling, how should I proceed this in Turbotax? Thanks
