when mailing, nothing will be available on the WMR tool until it has been scanned into the system.
if you use a tracking service when you mailed and you have indication it was received, then all you can do it wait. it'll get processed.
there is currently a backlog of 1.8mm paper filed returns. I suspect your return is in that pile.
