Chemistry question: Is there any household substance that has

Are you asking for pure calcium? You're better off trying to get an intermediate. What are you trying to do with it?

This or chalk, but I dont know how to remove the carbonate. My immediate thought is performing reactions to replace the carbonate groups with h20 then dehydrating it, but again I don't know how to do that.

You could consider outgassing it through high heat instead. I assume that to be easier. You'd have to aim for 800-900 degrees Celsius in an charcoal oven though.
Getting pure calcium would require you to do electrolysis and your best bet is to get it to smelt... long story short: I don't know how to get an impromptu setup for this.

chalk, marble, limestone...
Each will dissolve in hydrochloric (or muriatic) acid. Then you can selectively precipitate out the calcium ion

You can sometimes find CaF2 at the bottom of water jugs, It's not really a productive option although. Electrolysis is not really an option either by any means. I would honestly just buy it from ebay OP

you can suck all the calcium out with a straw

I watched this guy extract iodine from a bunch of seaweed he found pretty well with just stuff he has laying around while out panning for gold simultaneously. Maybe send him a message

He has a billion vids, maybe he has one for calcium somewhere. Seen him do it with exytracting metal rocks too.
