I would follow Audioguru’s advice, the filters do not need sharp roll-off because 38KHz is well away from audio frequencies and the first harmonic of the pilot is also well away from 19KHZ. What your circuit lacks is filtering on the audio output and on the 19KHz pilot tone.

What I meant by the levels not being different is that the 38KHz is a logic level signal, essentially 0V and supply line levels, it is there only to open and close the analog switches inside the Where this has an additional E suffix letter, this indicates the DIP package rather than a surface mount device. From the stereo encoder point of view, it should make no difference whether it comes from 4011gp based oscllator or a based one.

This usually results in destruction of the gate! I am not try to design a filter in khz range using LC because i dont know how to make a coil in range of mH i am not familiar to ferrite. No additional import charges on delivery. Need help with 38khz Oscillator can i ask?

Not so well with transparent paper. It should work equally well whatever the circuit generating the switching signal is, as long as it meets logic levels and has the correct timing. You’re covered by the eBay Money Back Guarantee if you receive an item that is not as described in the listing.
