Thanks, but the issue is more extensive than that.
In Turbotax Deluxe > Wages & Income > Business Items > Business Income & Expenses > Add Business, I can add one 1099-NEC, but when I add the next one, the first one disappears from all calculations.
This happens whether the 1099-NEC's are both for the same business, or different businesses -- even different taxpayers.
There is no issue with 1099-Misc's.
