Help piping find to cp

[Chocolate]

I have a directory with a lot of subdirectories that all have loads of files, I am trying to find all files created after a certain date and copy them over to a single directory elsewhere.
so far this is what I have but it’s not working for some reason
1find . -newermt "2020-09-30 20:42" -exec cp {} ./tmp/1 \;

any help?
