Answer 1

There is text field missing in code, so based on Trying to get the text field please specify to show and hide

HTML text-field

<label class="option" for="edit-submitted-distributions-fieldset-1-fund-distribution-select-1">other (please specify)</label>
<input id="edit-submitted-distributions-fieldset-1-widg-donation1otherdescription" type="text">

and JS code will be

$(document).ready(function() {
    $("#edit-submitted-distributions-fieldset-1-widg-donation1otherdescription").hide();
    $("#edit-submitted-distributions-fieldset-1-fund-distribution-select-1").click(function () {
         if ($(this).val() === "0000~0000") {
             $("#edit-submitted-distributions-fieldset-1-widg-donation1otherdescription").show();
         } else {
             $("#edit-submitted-distributions-fieldset-1-widg-donation1otherdescription").hide();

         }
    });
});

Fiddle

In JS code you are binding the label id="edit-submitted-distributions-fieldset-1-fund-distribution-select"

But to hide and show the text field if click on radio button like you said in question title, you have to bind the click function with radio button id id="edit-submitted-distributions-fieldset-1-fund-distribution-select-1"

and this $("#edit-submitted-distributions-fieldset-1-widg-donation1otherdescription").prop("disabled", false); only makes the input not disable, it has nothing to do with hide / show the input.
