If the amended return has a balance due on it then the WMAR? tool may not give you a status report. If you sent a payment with the return as you were supposed to then when they cash the check you will know it at least made it to processing. Once processed they may send you a bill for any penalties or interest you may now owe. With a balance due return the standard is no news is good news.
*** just learned a new trick ... don't know if it will work on the Amended tracking tool like it does on the regular WMR? tool but when asked for the refund on the 1040X enter in $1 as a work around to see the progress ***
