Transfer Dilemma

Beginning of the year I transferred from school A to school B however after a day of classes I realize i had made a mistake and this wasn’t the place for me so the next day I dropped all my classes before the add/drop deadline and transferred back to school A. I was wondering since it all happened before the add/drop deadline did I technically attend school b? and would I have any transcripts at all from school B and if yes would they all feature W’s or? I am looking at transferring to school C and it says to send transcripts from ALL schools you have attended so I am honestly confused what to do here.
