Como dizer "Entendi o que você quis dizer" em inglês

Hey guys! I'm back! xD

I miss talking with you... I'm so busy lately... ;[
You know... work, college, boyfriend... it's complicated! =X
But I promise I'll come here for more times. ;D

So... uh... about my doubt...
I was talking with a friend of mine, and I coudn't find a right way to tell her: "Entendi o que você quis dizer"
It's correct to say this way: "I understood what did you mean"??????
I also thought to say: "I understood what you meant" >> Is correct to say it too??
And... Can I replace 'understood' by 'got' in this phrase?? >> It'd be: "I got what did you mean" ??

I'm glad to post here again! xD

xoxo,

Jessy
