<p>Whenever I try putting the filament through the nozzle it does not go through. I have searched everywhere online and have found nothing.</p>

My first step would be to cut the filament at a bit of an angle.  This will help the filament enter the extruder correctly.
If you're still having trouble, you may have a clogged nozzle.  This article by Lifewire -

has some good info.
I've also heard stories about the Bowden Tube (the PTFE tube that guides the filament from the extruder to the hotend) becoming warped or melted in cases where the printer's temperature control went awry.  This is rare as PTFE doesn't melt until 320°C.
