Karen, sorry to read about what you've been through but glad you've come out the other side! Paul is one of the most knowledgeable and thoughtful people here and I always learn from his posts. He's given a wonderful primer on taste.
That said, everyone is different. My personal experience was that my sweet tooth returned more quickly than anything else. That is, it never actually went away. I found that the only things I was able to eat once I was able to eat solid food again - this was maybe 6 months after beginning RT - were completely bland and practically tasteless.
I made myself basic vegetable soup. Oatmeal. Blender stuff with milk, peanut butter, protein powder, yogurt, banana, etc. There are lists here on the forum I believe.
Shall I assume that you're getting your calories from nutritional drinks? I lived on those completely for 6 months and still make a meal of same at least once or twice a week.
Keep trying stuff and follow Paul's advice as much as you can. And keep coming back here with any and all questions.
Sending good thoughts your way.
