This is happening because the input text box is a little wider than the other options and hence one of your options is being pushed to the next row.
Try adding this code to addonReady and see if it works:
let all_rows = this.questionContainer.querySelectorAll("tr");
let target_option = all_rowslall_rows.length - 1].querySelector(".LabelContainer");
target_option.style.top = "-" + target_option.getHeight() * 1.1 + "px";

Thanks ahmedA . Looks like that may have done the trick:
Thanks for your quick and helpful response.

I spoke too soon I think. This solution worked fine for the survey when I was accessing via my laptop. However, it didn't fair so well when I used the mobile version. Here is how the question displays:
The text box is covered over by the last option 'Co-worker'.

Without the JS code the question appears as follows by default:
which is also strange because the list has switched order I originally had when the list was vertical. Here Co-worker is the last option. This seems to be reading across column 1 and column 2, then down instead of down column 1, and then across.

Yes. It fills column wise.
Here's a hacky workaround, encapsulate the entire code in an if statement:
if(document.querySelector(".LabelContainer").getWidth()/innerWidth > .7){....Code Here....}

However, with the ordering issue, I recommend creating a separate question for mobiles.

Thanks for your continued support ahmedA .
I added the code and now have this:
Qualtrics.SurveyEngine.addOnReady(function()
{if(document.querySelector(".LabelContainer").getWidth()/innerWidth > .7){
let all_rows = this.questionContainer.querySelectorAll("tr");
let target_option = all_rows[all_rows.length - 1].querySelector(".LabelContainer");
target_option.style.top = "-" + target_option.getHeight() * 1.1 + "px";}
});
Is this correct? With the code as such, I get the following on my laptop and mobile, respectively:

Sorry, that should have been a less than:
Qualtrics.SurveyEngine.addOnReady(function () {
    if (document.querySelector(".LabelContainer").getWidth() / innerWidth < 0.7) {
        let all_rows = this.questionContainer.querySelectorAll("tr");


        let target_option = all_rows�all_rows.length - 1].querySelector(".LabelContainer");


        target_option.style.top = "-" + target_option.getHeight() * 1.1 + "px";
    }
});

However, since you are still facing the ordering issue, I recommend setting up two copies of the same question. One for mobiles and the other for desktop. Then use Device Type display logic appropriately.

Thanks again ahmedA . I'm almost there :)
I added a 'mobile' version of the question and I think I'm good there.
Next issue (and I hope/think the last one) is when I have three columns. What changes need to be made to the JS code? I have the following question with three columns and the current JS code applied:
