You really need a new wheel , single speeds just have 1 cog ..
good news is you can start out with a pretty cheap freewheel wheel
I have taken old 5 speed wheels , removed the rusty 5 speed freewheel ,
changed the axle spacers to make them equal length on both sides , hub in the center.
then put the wheel in my truing stand, and took 'the dish' out
by loosening the right side spokes , tightening the left side spokes
so the rim is in the center of the axle width and also the hub flanges..
then screw on a single speed freewheel .
