Lost in the Field (Credit Analyst)

Without getting too into the weeds, I’m starting off 2026 with a mountain of shame and uncertainty. Essentially it is my 7th year as a “credit analyst” yet I have no idea on the correct way to read a tax return. It has forever been difficult for me to understand. I have legit fumbled my way to my position. Jump to today, I am expected to fully understand the ins and outs of tax returns and accurately demonstrate their financial position. I am a super visual learner but I haven’t been able to find a guide that could help me the way I need to learn. Is there any ideas of any guides or workbooks I can learn from?
