Realistically, they're talking about Hunter Biden. 
Any anyone else that pisses them off and for whom they think they could gain political mileage by releasing the tax returns and screaming from the Fox News pulpit:  "isn't it WEIRD that John Smith earned $350k for CONSULTING! People are asking questions about whether this is legitimate."
remember, that is a dangerous two-way street!

That's right; if they can do this to him, they can do this to Biden!
What's that? Already voluntarily released before the election? Over 20 years worth without any gaps? And every other president since Nixon, too?
