Why can’t I access my purchased music on iTunes?

I bought songs on iTunes with my money while having Apple Music. But when it expired, I could no longer listen to or download the music I purchased. I do not want to pay for the subscription to listen to music I bought myself.

I have checked my purchase list in the more section, but they don't even show in there.

Could someone possibly guide me to get the music back?
