This latest response from the QuickBooks team is a joke. If you eat through the thread, it’s not like the majority of people on this thread are newbies and have never printed 1099s before. The issue is that QuickBooks failed to produce a timely update and the update that did finally come through messed up existing 1099 mapping. Unfortunately, unless you can search by my username, I cannot provide a link to the solution that I found in the community. It was a strange workaround but it worked like a charm for me. Also, it was when I installed the much delayed update to print the 3-up 1099 – NEC forms (and I had to try the update three times because it kept freezing!) that this whole problem with the 1099 mapping started. Shame on QuickBooks!
