Soft Toggle Circuit with T-Flip Flop not working
After addressing the errors, you need to understand how to debounce a mechanical switch.  You can read about debouncing switches here and here. Basically you can use logic:



Or an RC timed circuit cleaned up with a Schmidt trigger:



Or (not as clean) just the RC timed circuit:



In all cases note how the switch is connected to one side of the power rail and a resistor to the other. When the switch is engaged the switch over rides the resistor pulling the voltage to the opposite power rail.

With few exception, the input to logic gates should not be ambiguous.  That is, they should be clearly at or near one or the other power rail.
