Would you be able to please give an example or screenshots of what you have done for the product page, and how you would like for this to look on the homepage?
Any further context will be helpful in order for me to be able to best advise you here.
At the moment from what you mentioned, I did want to share how you can add text boxes to your theme through sections. You can learn more about how to edit and add sections in our help doc on the topic here.
What theme are you using? Sections can differ for the various themes, but typically you will find something like Image with text overlay that will allow for a space for text on the homepage.
Again, if the above is not what you're looking for, please do fill me in on the details I asked for and we will look into this.
Let me know if you have any questions!
Thank you for the screenshot!
How did you set this up to work on the product page, was it using an app? If so, for this you should contact the developers of the app that you used since they would be able to best advise. I am unable to help you out with the custom coding involved in making those fields appear on the home page, but I can suggest you contact a Shopify Expert to look into this with you. They are freelancers who charge their rates based on the work that they do, and are able to help out with custom coding.
