Thank you for this advice. For both of my clients, the form has an entry of 1 for line H of the 990-T (number of unrelated trades or businesses). I don't have the option to right click, but I can double click and it will take me to the entry page. There is nothing there - the field is blank. There is no drop down - do I enter "none?"
That takes you to the section for Form 990-T Miscellaneous.
Scroll through that section and you should find some entry to remove.
If all else fails look to "Return actions" and select "Send to Intuit" so they can analyze and repair.
Under General > Misc. (990-N, 990, 990-PF, 990-T), under the Form 990-T section, do you have any input at all? If so, remove all of them (assuming you don't have any corresponding entries for income and expenses elsewhere in relation to the unrelated business).
Still an AllStar
