Generally, yes. But you may need help, and you haven't provided enough information to know what is really happening.
An audit is a big deal, you go in person, they tell you what is wrong, and they give you a letter at the end explaining what they did. These are very rare.
More common is you get a letter proposing a change to your tax, and giving you 30 days to reply with a payment or with documents and an argument (all by mail) as to why your return was correct. Sometimes these notices are a little hard to understand, because they use computers and shorthand, but you can decipher them with a little effort. (But, if you get a letter, and ignore the deadline, the assessment becomes final and it is much harder to dispute.)
What has actually happened? You had an in person audit, a mail audit, or a letter (CP notice) proposing a change? What is the notice number and what does it say?
I am a ihss provider for my grandson so taxes are not taken out of my check. I can still claim earned credit. I also work part time and made $6400 for the year so they audited me and did not count the income from IHSS and reduced my earned credit and child care
