Not work how? You need to tell us what kind of errors you see, otherwise, we can only guess.
I'd lose the file() construct. It sets up a connection object, which can be less than useful when read.table reads the file several time in order to decipher the column structure of the file.
filepath1 <- "/Users/michaelfeher/Documents/R Documents/COVID19/20200906-1822-total-cases-jones.data"
should be OK, provided that the file actually exists. In particular, check that the space in "R Documents" really is a space and not something that just looks like a space (no-break space is a common culprit).
If you can read the file, but it comes out weird, then you need to diddle the arguments to read.table, e.g.
> filepath <- "~/tmp/R files/test.data"
1 x y
2 1 2
3 3 7
4 9 13
> read.table(filepath, header=TRUE)
1 1 2
2 3 7
3 9 13

Most people don’t use absolute references. They set the working directory and then just use the name of the file. See under the Misc menu.
