In your opinion, was the $20,000 cash payment enough to make up for the experiences of Japanese Americans during relocation and internment?

No, the 20,000 USD in cash were not enough.

Explanation:

During the World War II, the United States did something that resembled a lot to what the fascist states did. They targeted one particular group of people because of their origin, and without having any proof for their suspicions, they acted and violated their human rights.

The people of group in question were the Japanese Americans. They were sent to internment camps just because the US government thought that they might be collaborating with the Empire of Japan, though they didn't had anything to support their claims.

After the war ended, the Japanese Americans were released and were compensated with 20,000 USD in cash. And while the USD had much higher value than now and those money were considered as very high amount, it doesn't mean that they solved the problems. The Japanese Americans were seen with suspicion, they lost jobs, their businesses crumbled, so those money were not enough as they were socially judged and isolated.

because they can and they wanted to.
