I asked this question once before, but I did not receive any feedback on solving on the issue and I am still confused as to what I am doing wrong.
I found a public domain map of Florida counties on Google. All I want to do is add coordinate points from a cvs file to the map. It should be simple, right? Apparently not. I made a cvs file with latitude/ longitude and x,y coordinates, but the points do not line up with the map. Yes, I DID have the same projection for both layers. The counties map had a projection of EPSG 2237, NAD 83/ Florida West (ftUS), so I changed the cvs file to have that same exact projection. I also made negative values for the longitude coordinates for United States. I tried this with various Florida maps to see if the counties map I found was just wrong, but every map I tried had the same issue. I tried various types of x and y coordinates for the points, and nothing was better. This really should be a simple thing to do, so I really would like to know what I'm doing wrong.

If the county map is in EPSG:2237, better leave it that way. DO NOT use
Set Layer CRSto change it, that will corrupt your data. If you did, change it back. Better useSave As ...for vector data andRaster -> Projections -> Warpfor rasters. Both need another filename and a different target CRS.If you are unsure, set the PROJECT CRS to EPSG:3857, and add an OpenStreetMap background with the QuickMapServices plugin. Then you see which of your layers is correct and which is not.
UPDATE
Your sample points seem to show up at reasonable locations:
