I agree, it appears to be actually referring to Form 1099-NEC. This form was new in 2020*. Before that, its function was combined with Form 1099-MISC.
We already have lots of questions tagged form-1099-misc, and almost all of them apply to the new 1099-NEC form. The two forms are related, and even share one set of instructions. I think my recommendation is to make form-1099-nec a synonym of form-1099-misc (or the other way around), edit the tag descriptions to make it clear that the tags apply to both, and get rid of this new form-1099-ent tag, which seems to be erroneous.
I have removed the form-1099-ent tag from the two questions, and tagged them with form-1099-misc. I have held off creating a new form-1099-nec tag until we can come to consensus here how we want to handle it. I have asked a new meta question to discuss how best to handle these tags.
* Actually, it existed in 1979-1982, and was brought back in 2020.
