Just wanted to update this thread, in case somebody else is having this issue lately. I had to call Intuit Support, verify my account, then the lady helped me by going to "Help -> Reset Intuit ID Settings" from there, click Ctr + R, which opens a window called "Set Realm ID." The lady told me a new realm ID to enter, then I had to log into my Intuit account (email, password, code sent to phone). Once the realm ID was reset, I clicked "Send" on my payroll, entered my PIN, and it worked. Very easy fix. Just get ahold of someone from support who can give you the correct Realm ID.
