Hi Carla

Thanks for posting in the Lucidchart Community! I'm sorry for the trouble but I am happy to help. Unfortunately there is not a way to export your document to include comments. However we're always looking for ways to improve and you can submit a feature request to our product team here. As a workaround you can share your document with comment/edit access to allow others to view and make comments on your document. Let me know if you have any questions.
