I have one child and I claim head of household. I gross 23,000 and I claim a 2 on my withholdings. How much should I expect to get on my return? And shoul I expect more if I worked a lot of overtime?

Need to know what was withheld to determine your refund.

Due to your income level, you will get the Earned Income Credit of a few thousand plus the $1,000 Child Tax Credit.
