And no water is making it out the condensate lines in photo 2 and out the drain line.

Call a tech out most likely secondary exchanger is leaking

Thank you, and update, the 16x25x1 filter was absolutely dirty as fuck. Like caked. So maybe can lack of airflow cause this possibly?

I changed the filter and flipped the heat back on. It'll run overnight and I can check on it again tomorrow.

Make sure you have CO detector that works

If the A/C was on then yes, it could be airflow. If you’re just running the furnace, it’s either one of those black lines leaking, or you’re calling a tech out

Does Goodman/daikin sell just the gasket?

I’ve replaced just the gasket so should be able to get it if not replace collector box

At least with my local Daikin supplier…they’ve never had just the gasket. I’ve had to replace the entire collector box that comes with a new gasket

Collector box gasket needs replaced, extremely common on this model

Sometimes you can tighten those screws back down but it's likely you've lost your collector box seal or your inducer gasket. Neither are very expensive to replace and just require a nut driver and some silicone. I'd advise having an hvac tech do it but if money is tight you can do this yourself if you watch a video and take your time with it. This job would take me maybe 30 mins and a homeowner about an hour.

The worst case is that secondary is leaking and you should have it inspected and possibly flood tested for safety concerns. If secondary is leaking you'd probably see water in the blower compartment. It's possible an obstructed drain can be contributing to this but would normally set off the pressure switch that the gray hose on the bottom of the box runs to.

New gasket, very common with goodmans. Actually very easy fix

Two options here. You call a tech and have them order a foam gasket that will likely do the same thing in a few years. Or you pull the inducer and the secondary cover, get some high temperature red RTV silicone and reseal it yourself. While it’s not a “hard” fix, it can be a dangerous one if not done properly. Sometimes screw heads get rusty and snap off. It can be done but can be tricky.
