I was able to go to the business (Select EDIT for the business on the list)
Scrolled down to Business Income
Selected "1099-MISC Income" and entered a 1099-MISC with an amount in box1 and also a 1099-MISC with an amount in Box 2
Nether caused an issue
Could you try entering the 1099-MISC directly in the Schedule C section to see if this remedies the issue?
