Business Went Busted, Crypto Dropped, Recover My Cost!

Hi all, hope all is well.  I have a few questions while using turbotax, please.
1- I invest cash into my friends power washing business and soon after he passed. I lost my money. How so I show that loss?

2-I invested in crypto and the last time I checked, my money was at half the the value. Is that a loss or do I need to wait until I sell?

3- I remolded a house and rented it, I haven't broken even yet.  Do I have to show the income even though I haven't paid back what I owe?
