Are my income taxes and my stimulus conjoined into one check? Because I never had my stimulus. I filed my taxes and they gave me $1848 1200 600 but is the $48 my taxes?

I never received the first stimulus checks. So when I filed my taxes TurboTax added the $1200 from the first stimulus and the $600 from the second it then said my tax return is $1848 but I wanted to know is the $48 what I paid in taxes? Or am I missing the money that I paid for in taxes?
