If I have been praying a certain way my whole life and I found out that I was saying the wrong word. Would I have to make up those prayers?

Here there three situations according Aagha e Sistani
1- if he was jahil e Qasir the one who was somewhere there was not any possibility to learn correct salat then no need to repeat but if he was able to learn but did not learn then he has to pray again in correct way here again three situations
1- repeat all prayers in correct manner
2- or contact office of the marja and explain he will guide in this special case
3- if repeating of all is very difficult then pray the amount which is possible and for rest do isteghfar
