I tried filing my taxes and it gave me 0$ in return why?

Extremely unusual. Hardly ever comes out exactly even. 

@cece9770 We cannot see your screen or your tax return.  Without giving us any of your personal information like SSN, etc.----what income did you enter?   Did you enter taxable income?   Did you have a W-2, Social Security, retirement income, etc.?    Was tax withheld from the income you entered?

Usually you will only see that if the only income you have received is from social security or the VA and is under the threshhold for filing.  without knowing more specifics about you AGI, it is impossible to give you better feedback.
