Did the site ever update to say that the check had been mailed? Or did it just say "Your check has been scheduled to be mailed on X date"? That's what I get even though the check should've been mailed May 1st.
Check my original post, mine was unique. It said mine had deposited into my account on X date. Since that account was closed, the check was mailed to me. The site never once updated to say it was being mailed, the only reason I knew it was is because in the FAQ it said if it's deposited into a closed or frozen account (mine was frozen), if the bank rejects it (they did), the IRS will mail it. Took about 2 weeks from the day it was sent back to the IRS by my bank to get the paper check.
