I read somewhere to try this:
Go to Riverwood Trader and drop the stolen item, pick it up with holding A or Y and then drop in near Camila, she should take it and then place it into your inventory.
Not sure if it works for ALL stolen items, about to try it with the Commentaries.
I do it a different way, I simply sell them the items, and then re-buy them back. Since I have over 300,000 gold, its a fast and easy way. Oh, and I have the perk where I can sell any stolen items to anyone.
