Hello @kevinlampron916
Thank you for getting in touch with us!
Let me tell you that in the new checkout layout that is Modern Checkout style, we have modified the account creation fields display working.
So, I checked the shared checkout page and it seems that the account creation fields are not displaying because you might have set the options to auto-generate the username & password in WooCommerce -> Settings -> Account & privacy tab.
Due to that setting, the username & password will be created automatically and if the user wants to create an account a checkbox is displayed to opt-in for it.
Here is the video for the reference: https://share.getcloudapp.com/wbuz7REW
I hope this helps you.
Please let me know in case you have more questions or doubts. I will be happy to help.
