My minor children received a 1099-r from a life insurance policy they have no other income. do i need to file individual taxes for each child so this money gets claimed?

the gross distribution is 1225.04 and the taxable amount is 391.72 if that makes any difference.  I have 4 children who all received the same amount. When I enter all of the information under the kids information with the 1099R there is no tax due so I am just unsure if I need to file the return to claim the money or since it is under $10350 does it even have to be claimed. Please help!!!!
