Dcmef - I am able to print 1099-NEC in the 3-Up format yesterday and today with QBD 2020 R13. The alignment is a little wonky, but I was able to adjust enough that it should be usable. Hoping they fine tune it a bit before I print the majority of my forms in the first week of January. I am upset that the change in format was not widely publicised by either the IRS or Intuit. I had to run out and purchase the new format forms, when I already had a supply of the old format that I will now have to toss. I also realized that I don't have the appropriate envelopes for the 3-Up format and have to buy those as well. I have several hundred 2-Up envelopes and only a few of those forms to mail, so wasted money on buying those as well. Not happy overall.
