Unfortunately it is much more likely to be a Chinese Chestnut, as they're widely planted and have escaped cultivation in some areas.

You can use the  VA Tech dendrology key to separate the two species: https://dendro.cnre.vt.edu/dendrology/idit.htm

The American Chestnut Foundation has several ID keys on their website to differentiate one species from another.

If you would like to send us a close up of the leaves we can try to help as well.
