They don’t say why the US hasn’t paid out yet, and the way it’s stated in this article and the linked article inside implies that it’s a failing on the government side.

With the significant delays and attempts to bring in off shore labor, it’s much more likely that the factory hasn’t hit the targets needed to receive the subsidy.

The government is using the cash as an incentive to build the factory, not just handing out cash for no reason. Just like the Foxconn factory that failed in Wisconsin, they need to hit milestones to get the money, it doesn’t get handed out upfront, otherwise they’d risk a company just taking the money and running.

The US was trying to scam TSMC. So what happens next? Will TSMC still build its fab in the US?
