This is not an American chestnut. It could be a hybrid by the tree form but the leaves are too waxie, like an oak. The leaves do not have the same fishook pattern as an American and have the profile of a Chinese.
If anyone is interested in identifying information I have an email with side by side identifying pictures. Just email me firstname.lastname@example.org
Also, SUNY-ESF in Syracuse has developed a blight resistant American chestnut through genetic ingineering that should be approved for distribution in about 3 years. See pictures of American chestnut leaves and pictures of the new blight resistant seedling, that were inoculated with the blight, 3 weeks and 6 weeks after inoculation https://theconversation.com/new-genetically-engineered-american-chestnut-will-help-restore-the-decimated-iconic-tree-52191
