I am having the same problem and calling support didn't help either they eventually just hang up... BUT I found a work around! Exit out of the wizard for preparing 1099-NEC and start up the 1099 wizard again but choose 1099-MISC just leave all the vendors selected selected and advance to the mapping screen. Use the drop down to change from showing only 1099 account to showing all accounts then change all the accounts you need to map as NEC to "omit from 1099 mapping" here in the MISC screen. Then save and close. Start the process over with the 1099-NEC and once you get to the mapping screen check the box to map them all in box 1 and all the accounts that you'd changed to "omit..." in the MISC process should now be "Box 1 Non employee compensation. This worked for me, this year end season has been so frustrating with qb not working smoothly, I've never commented on any of these but dang this has been a pain!
