May have claimed head of household?

So the deduction for head of household is 9300, my deductions were 9253 is there a way I May have claimed head of household? I thought I didn't. Or would the 9253 be a combination of other deductions? Its been 12 days since i filed and I have yet to receive either state or federal and I know of people who got theirs in 10 days or so. I had gambling winnings would this slow the process?
