I have my 2nd floor HVAC in my attic. The condensate drains by PVC to the
basement. Recently, the line to drain the condensate has been leaking in the
soffit of the 2nd floor.

My question is can I have it drain into a vent stack? Or can I drain it into
a utility sink on the 2nd floor?

It would be fine to have it go the utility sink or any drain line.
I believe code would want an air gap at the sink. The good thing
about the sink would be to visually verify flow and also to verify
efficient cooling.

Mine is draining into the vent stack passing through the attic. There is
a p-trap (or whatever it is called in a horizontal line) in the 1" pvc
drain line. Of course, the p-trap water evaporates between Summers, but
I have never smelled sewage in the attic.

Your local building department might require a trap primer for such an
application. Here is an example;

The IRC requires that condensate be piped to "an approved place of
disposal". This would *not* allow it to connect to a sanitary waste or vent
system. It can drain to a indirect waste or just be piped out onto the
ground. It could also be connected to the downspouts I would imagine. But
legally, it can not connect to a vent pipe. (It's not just the smell or
sewer gas you need worry about, vents carry deadly bacteria as well.)
