Are you sure it's water and not coolant? This is a typical location for a heater core leak.
If the car is a '23, is in not still under warranty?

 

I've had my car parked at work when it was raining. when my shift was over and I got in my car, there was water sitting in the floor on the passenger side. I took the car to two different dealerships, and told them my issue. The first cleared the AC drain line. but said there was never anything blocking it, and the other inspected the windshield for a bad seal. They told me that the seal was bad on the bottom of it. Before they even inspected it they told me that Toyota does not cover the windshield if something is wrong with it, regardless of warranty. Safelite told me they frequently have people come from dealerships saying they have bad windshields, and to have them replaced regardless if it's true or not.

 

Also long shot here but can you find out where the previous owner had the windshield done at? If so maybe they will honor the warranty as that would most likely be lifetime on the work putting it in. If you ever see what they do to put them in, it's a big squirt of that urethane adhesive that seems impossible to mess up but here you are...

 

As someone that is a tech at a Mercedes dealership that replaces windshields I do not trust safelite. I have seen too many botched windshield repairs from them. That being said if you have the cowl out it might make sense to do your own water leak check and make sure the cowl drains are working and not clogged and backing up into the hvac system.
