Check your panel diagram for compatible breaker types. It will also tell you which/ how many breaker slots are able to be replaced with tandems. If you upload a pic of your diagram I could help more.
You might have better luck with square d or Bryant af- tandems and depending on your CH panel, they might be compatible.

These CH breakers should be compatible with SquareD Homeline (HOM) breakers (make sure they say HOM and not QO). Eaton breakers would work too, but i'm not sure they have as many tandom options as square d.
I can't tell if your panel is compatible with tandems yet though. Can you show me the picture diagram that should be right next to all this? it'll have a bunch of squiggly lines beneath a main breaker. slots that have 2 squiggly lines instead of 1 are compatible with tandems.
Sometimes it'll tell you how many breaker slots there are and if it says 20/30 slots then 10 bottom slots can be tandem, or 20/40 means all slots can be tandem.

My panel sticker doesn’t come with that diagram. Only thing next to it is a door directory for labeling circuits.

Also the 60amp car charger for the Tesla isn't always necessary. I plug mine into a regular garage outlet overnight and have never needed the lvl 2 charger.
level 1 charges ~7miles every hour (84 miles if you charge 12 hours overnight, which is more than most people's daily commute)
60 amp level 2 chargers ~36 miles every hour (full charge pretty much guaranteed)

Yeah it’s my wife’s car and she commutes far each day. RT is probably around 150mi. Don’t want her having to rely on SC if she can it topped off here reliably every night.

Word. you might want to go the sub panel route. Might be beneficial to hire an electrician
