Oh "to know"?

Sí.

and I also found out that "yo se" is "to know"

You’re close, it’s I know. Saber is to know. Comprender and entender are slightly easier to conjugate because saber is irregular:

I know - yo comprendo - yo entiendo - yo sé
You know - tú comprendes, entiendes, sabes
He/she/it knows - el/ella comprende, entiende, sabe
They know - ellos/ellas comprenden, entienden, saben

*linguistic tidbit- ‘you’ is the formal version of ‘thou’. So while Spanish uses tú informally and Usted formally, modern English only uses the formal, contrary to popular belief.

hippy in reply to @snottyotter

saber

I just did that in duolingo last night and can't remember what it is.

@hippy - I am the same with Duolingo. I think I am not taking it in but it is not until I go back to practice (the broken icons) that I realise I must be retaining something. The wine doesn't help though!

Does anyone know a really good source for verb conjugation? I would like some kind of download that I could print off.

I think there's slight differences in meaning but not loads, comprender being almost a cognate of comprehend, entender being like understand, so you really get it, saber as to know, like a fact or skill or something. Also have creer which is to believe but works like to know a bit, and conocer which is to meet or know a person or maybe a place.
