Confused about

So my question is this. I'm a waitress and don't really make much as it is. I paid taxes and filed before the tax thing happened.  I spoke with someone (tax specialist through the turbo app who said I'm due a refund on my unemployment taxes. Then about 2 was ago I finally got ahold of someone from IRS who said that I received all the credits that were available so I'm not due a refund.  Now this makes no sense because bottom line is,  I paid for something that I really didn't have to...

 10,200 worth of taxes.  I'm HOH, 1 DEPENDENT and my AGI is 23,000
