EPSG codes are specific to the lidar data file set you are using. This being a course in NC, you will probably not be able to get lidar data from the usual places.
update edit: I have built quite a few courses in NC and you are going to have some hurdles to overcome with this course. When you do find the lidar data, it will not match up with any of the satellite imagery that OSM has available. You may want to map out a single hole in OSM that has elevated tees and a couple bunkers that will give you reference points so you can determine how much x/y coordinate adjustment you will need to make (this is also why you really need tgc2019) for the splines to line up with the terrain.
Plus, this course specifically doesn't have any golf features on most of the imagery choices, so this possibly creates additional issues when trying to map out features that may be present in the lidar data, but not represented on whatever imagery you have available to use for mapping.
Let me know when you have the lidar data and hole mapped out and I'll see what I can do to assist you.
update 2: This course doesn't seem to have any bunkers or elevated tee boxes. You may be able line up with one of the water hazards on the course but that can be very unreliable.

Mal - thank you so much for looking into this. This was my home course growing up, hence why I’m trying to recreate it. The course was closed a few years back which is why most of the imagery in OSM is so bad. Google maps has a great image, so I was hoping OSM would have similar, but no luck. Fortunately, I know the course really well, so I’ve been able to do okay mapping.
I am working on mapping in OSM, and have downloaded a copy of TGC2019. I’m not sure where to look in the LIDAR file for the metadata. If you could help on that, it would be great.
In the meantime, I’ll continue mapping and let you know when I have a hole finished.
On last note, this course was very close to both TN & GA. I’m not sure if it would show in in LIDAR maps for either of this. I will try to look and see what I can find.
Thanks again for all of your help!

Do you have the lidar data? If you do, post a link to one of the las files and then I can open it and tell you what the EPSG code is. Again, EPSG codes are specific to the exact set of files you are using and there could be multiple sets of data that cover this area.
