Removing White Left in Transparent Background

[Katherine29424693xm9y]

I designed a logo and would like to make it sit on a fully transparent background - when I export it with a transparent background there are pieces of a white background left within it. How can I fix this or what should I be doing differently? I'm beginner level.

Looks like Select All and click None for Fill should do the trick.
