PH & TA are both really really low. And CYA is really really high. You can deal with then in either order, just do the PH fairly soon.
The best way to raise both PH and TA is with borax, but washing soda is fine if you want to use that instead. The TA test turning red right away means that the PH is really really low, down below 5. You want to raise that up, but not overshoot, so it is best to add a batch of perhaps three or four pounds of chemical at a time, give it an hour to mix in, test the TA to measure progress if PH remains off the scale low. The TA will start to come up before the PH gets in range.
To get CYA down you will need to replace water. You can get an idea of how much by doing the CYA test again, but this time mix equal amounts of pool water and tap water, test that, and multiply the result by two. That won't have much precision, but it will give you a rough idea if the CYA level is around 100, 150, or 200+.
