DXF location loading error on QGIS 3.14

I am working in a project that involves data from different files types, I managed to load TIFF and .Gz file (ordinance survey mastermap topography) to correct location. However I have a DXF layer that also needs to be overlayed but when I import it, the location is nowhere near the other two layers. As far as I can tell all my CRS settings are correct. Does anyone have any ideas what I can do to fix this issue?
