If Lightroom thinks the file is in the catalog, then you should not re-import, it is not a good idea, it causes more problems than it solves.
You should find the file in the catalog by using the following four steps in order
- In the Library Module, go to the Catalog panel on the left, click on "All Photographs"
- Expand all stacks
- Turn off any filters (ctrl/cmd-L once or twice)
- Search for the photo in the Library by file name
Thank you, I just found it
I appreciate the help!
