Late 1099-misc just received
I just received a late 1099-misc from a medical clinical trial my children are on. It is under my name as my children are minors. It is for $690. As my 2 children each earned $345. I have obviously already filed my taxes so do I need to amend now that I received this 1099 after the filing deadline? The date on the stamp is 4/14/22 but arrived today 4/18/22.
