You may also be eligible for earned income credit. That is designed as a help to low income earners. To be eligible, income must be earned from work (not investment or other passive income), and EIC is paid on a sliding scale -- it phases in at low income levels because you didn't work much, phases out at high income levels because you don't need it, and has a sweet spot in the middle with the maximum EIC.
You really should just file a tax return and see what you get. You may want to use the TaxFreedom edition. If your income is less than $31,000, you can file using the TaxFreedom edition, which includes complicated forms not normally included in the "regular" free version of Turbotax. The IRS requires it to be a separate web site. https://turbotax.intuit.com/taxfreedom/
You must create a different account to use TaxFreedom, you can't use your existing Turbotax account. You may also need to clear your browser cache and cookies. https://ttlc.intuit.com/replies/3491786
