Received email that my e-file submission has been cancelled and I need to fix the error they noted, however when I log in, there is nothing to select to fix?

I had the same thing happen to me in regards to Rental Properties and Royalties (Sch E).

Hope that they basically cancel the submissions in a day or so so that it can be fixed.
