Please provide more information:

The site is https://www.vividstyles.com and the “by Amie” appears throughout which I would like to remove

You can do this with a simple modification to the style.css file of your theme. Put the following code in the file:

.authour {
display: none;
}

One way to make the modification is from the admin panel of your WordPress (Appearance menu>Editor sub-menu)

Note that it’s recommended that you use a child theme of the original one. Otherwise, all code modifications will be lost when you upgrade the theme.

Hope this helps.
