You need to look at the data sheet.
The 74LS75 is not designed to source much current, it's much better at sinking current (out high source is rated at 3.5V, 400µa. while the out low sinking is rated at 0.2V, 16mA)
So, to use that, you should connect the LED cathodes to +5V and the resistor to the latch output.
You then turn on the LED with the output latched low.
I think the best way to go about it s you download proteus 8 professional EDA and draw the circuit where simulation will be factored in and more improvements can be done easily. If you dont know how to use proteus you can learn it here https://www.theengineeringprojects.com/category/proteus
