After you file

Oh, now I'm really confused.  I'm filing my deceased mom's final income tax return (1040) using her SS# (not the EIN).  I won't be filing her final Estate tax return until September.  Since the income tax return will have her Social Security number, I guess the income tax refund cannot go into her Estate account (because the Estate account uses the EIN).  This is so complicated!  I can't use Form 1310 either, because none of the boxes apply to me.  I am the Court-Appointed representative.  Box B on Form 1310 is for court-appointed representatives who are filing a 1040-X.  I am not filing the 1040-X.  I'm just filing her 1040.  I can't possibly be the only person who is in this situation.  Should I hire a tax attorney to help me with this?
