[Qgis-user] georeference intersecting lines of highway map

[John W. Blue]

I have downloaded historical highway maps in .png format that I would like to georeference.

Around the perimeter of the map are a few lines indicating lat and long making it easy to be able to add a layer to draw straight lines from left to right and from top to bottom.  Which I was able to do.  From there I was able to get QGIS to find the intersections.

And now I am stuck because I cannot save the intersections with lat/long coordinates it only allows x,y.

I am sure I am most likely doing something wrong out of the gate but this seems like the logical direction to go in.
