Is there any update on the fix for this?  I tried to file the 941 quarterly + schedule B today (21st July 2021).  I too am getting do not file draft message.  I have completed a full manual update in help, shut my QB desktop down & then restarted.  I still get the same message.  I see the recommendation is to do it manually on a handwritten form but that is just not do-able when having to also complete the schedule b.  Any suggestions/updates would be most welcome as the deadline is fast approaching to file.
