Q. "The thing that is confusing to me is that in 2022, I did receive the LLC, and I wouldn't have owed anything that year either".
You may have had a tax liability before the LLC was applied. And the LLC, you received, was more than enough to reduced your tax liability to zero.
You may have mistakenly claimed the American Opportunity Credit (AOC) in 2022.
If 2022 was the year you received your bachelor's degree, any graduate tuition, later in the year, would have qualified for the AOC (because you had not finished 4 years of post secondary education before 2022).
