Hi WDD,
Here's an article from EveryDay Health that might help your search for answers https://www.everydayhealth.com/mens-health/the-myth-of-too-much-testosterone.aspx It lists health issues and symptoms linked with excess testosterone.

You also ask for information about testosterone producing tumors. Here is some information from the American Cancer Society on Signs and Symptoms of Adrenal Cancers https://www.cancer.org/cancer/adrenal-cancer/detection-diagnosis-staging/signs-symptoms.html

Have you talked to a doctor about your concerns?
