Sled ran fine until left key on not running for a day. DEAD battery

Attached 2 AMP trickle charger to wrong terminals for less than 15 minutes.

Now really dead … was able to get light on dash before FUBAR.

Sled in storage so charger left on correctly for a while.

What did I fry? Or just get new battery? Just charge it like now and see what happens?

Depending on the battery CHARGER, you may not have hurt anything. Most chargers built in the last 10+ years are smart chargers, which is usually a pain in the butt because they wont charge a fully dead battery. They need to see a minimum voltage before they even start charging. many of them also have the ability to see if its hooked up wrong.

If its an old school charger that puts out amperage no matter what then the battery might be junk. If the battery is less then 3yrs old, see if it will take a charge with it hooked up correct. If its older then that I would just buy a new one and start over.

Check fuses

Many times when reverse polarity is introduced to a system from a battery charger, it pops a fuse if the battery was hooked to the sleds cables.
