Inherated IRA

My Mother Passed in March. I received a Inherited IRA . I had to open up my own account within the same Institution to have the Inheritance transferred then I cashed the money out.  I was doing my PA taxes and I put the code 4 down as Directed. But there was no distribution reason that matched Inheritance IRA  So I put the default reason. I am getting a return of exactly what the Inheritance amount was.  what happens now. I do not know if I did something wrong...
