Technically form 1041 has to be filed for the estate; the income tax return for the estate. However I think if you added it into mom's personal return the IRS won't give you a hard time. The tax on $611 is peanuts anyway. Whether or not an estate tax return has to be filed can't be answered since we don't know the size of mom's estate.
Please accept my condolences for the loss of your parents.
