2018 tax
I have prepared a 2018 tax return and it shows that I have a large refund. I have not paid any taxes for the year 2018. Is this a mistake. My tax status changed this year to head of household with 3 deductions. My daughter passed away in Jan of 2018 and my two surving grand daughters lived with all of 2018. I have custody of the 17 yr old and she draws social security which i=I understand it is not taxed.
