Sending in Transcripts

Hello!
I’m going to be applying for college this upcoming summer/fall to the following Florida Colleges:
-Florida Atlantic Univeristy
-Florida Southern
-Univeristy of Miami
-Jacksonville Univeristy
I was wondering, how do I send in my transcripts? I know my guidance counselor does it, however do I have to contact her, then have her send them in or do the colleges I applied to contact her and request my transcripts, then she sends them in? I’m pretty uncertain on my role, and am becoming nervous. Thank you all.
