Only reform Jews in America and they require jewish upbringing. I would recommend sillysaurusx going trough the conversion process at your reform Synagogue. (Reform is mostly about knowledge, basically classes). It’s there for a reason, you learn a lot if you didn‘t have an upbringing.

My situation was similar, matrilineal but my mum is baptized. I wasn’t required to, but I am glad to understand now what rabbinical judaism actually is.
