String replace in a value

I have some checkbox options which return values like this:
address1, address2, postcode
I’d like to remove the commas in the returned values and replace with a line break.
This is where I’ve got to, alas it doesn’t work.
<?php echo str_replace(', ', '<br />', get_field('myfield', 'option')); ?>

get_field() for a checkbox field returns an array of values, not a string. the_field() outputs a comma separated sting because it is attempting to stringify the array.

echo implode('<br />', get_field('my_field'));

Thanks John for the reply, however I don’t think I was very clear in my question.
This is how the whole checkbox selection is set up…

address1, address2, postcode3 : selectA
address4, address5, postcode6 : selectB
address7, address8, postcode9 : selectC

so the if I check selectA the whole value I get back is “address1, address2, postcode3” rather than an array (I think).
That’s the part I’d like to remove the commas and replace with a line break.
Thanks

The checkbox field is still going to return an array. https://www.advancedcustomfields.com/resources/checkbox/

$values = get_field('checkbox');
if ($values) {
  foreach ($values as $value) {
    echo str_replace(', ', '<br />', $value);
  }
}
