The procedure of making Sajdah Tilaawah

Q. After reciting Quran at the prostration parts, I used to do Sajda Tilawat by saying the Takbeer and then Sajda. However, I had never done the Takbeer post Sajda as I previously did not know the method included a Takbeer post prostration as well. My question is, do I have to repeat all my Sajda Tilawat?
