Is there an efficient way to file a 2021 tax return for an indigenous home repair & maintenance sole-proprietor, with zero expenses & net income of less than $3,000?

I'm indigenous to Nevada, residing at the Walker River Paiute Reservation suffering from the uneducated tribal administration's lack of comprehensive work. My goal is to receive the Recovery Rebate Credit, since I have not filed a 2021 tax return. Please help, as I am a friendly & humble American citizen.
