ESOP Distribution to child after death of parent

Looking for guidance on ESOP distribution to child after death of parent.

 

Questions:

  1. Does child need to file tax return if elects to cash out? 
  2. My understanding is there is no penalty for distribution after death however will be taxes as regular income. Is my understanding is correct?
  3. Does child have the option of opening up own IRA to roll over funds vs cash distribution? Child is 14 yrs old.

Thank you for the support!
