How do you align the submit button to the same line?

I have a single-page contact form, and I’d like to be able to place the submit button on the same horizontal line as the text field.

Unfortunately, this is for some reason incredibly difficult to do, I’ve tried editing the position of the submit button from the typical admin panel and also in the appearance customization options and I see no way to do it. When I try to do it in the form settings, the submit button does not perfectly align, it’s off center from the text fields.

How can I 100% control the location of the submit button in a form?

Hey Daniel,
Could you please share your website URL so I can further investigate to resolve the issue?
