I agree with @IlzeL and others who say this is a failure in the software. We pay extra for software that will allow us to accurately report our income and expenses and therefore it should provide us with the tools to do that.
Businesses receive government grants all of the time and so this is not an uncommon income situation. I would also point out that TurboTax already has a means for linking 1099-Misc and 1099-NEC to business income so this is not something new.
I believe we are owed a better explanation and/or an update.
