The circuit consumed 200 mAHr in 24 hrs? Or about 8.3 mA of a continuous draw?
The LM2576 indicates a WORST CASE standby current of 0.2 mA...so you clearly have a load somewhere draining the excess current.
But we can only guess....
Therefore, to properly assist you, a complete schematic with component values is required.
Edit: For instance, the 10k pullup on the output of the 4013 is not required. The 4013's output is a totem pole, not an open drain.
You could have other issues like this.
