You would need to call your parish and ask.
In my parish we have RCIA year-round. That means we had some people who received their sacraments last night, we have others who are preparing to be received into the Church during the Easter season, we have some catechumens who are preparing for next Easter, and we have inquirers who will receive their sacraments at some time in the future. People come in and go out at various points during the year.
In some parishes they have everyone wait to start at one time and move everyone along together.
If you are already Catholic and haven’t been confirmed, you might ask if your parish or diocese has an adult confirmation program. RCIA is not the best place for a catechized Catholic.
