Do you need the "deshita"? Can't it be disregarded as "desu" usually is?
I think disregard wasnt the word you were looking for but thats a whole different language. "Deshita/でした" is desu/です in past tense, so its used to say "yesterday WAS whatever" instead of y
"yesterday IS whatever"
Disregard works fine in what he asked, and what you said had nothing to do with the question he asked. Disregard as in remove because it's unneeded.
