Do I need to file an income tax return for earning $8215 plus $7644 from Social Security?

Is the $8215 reported on a W-2, or was it self-employment income?

It was reported on a W-2.

Which state? Are you married? If so, did your spouse have 2017 income?

California, No, I'm not married.

You do not need to file except to recoup any taxes that were withheld.
