Then plug in historical CPI values from above. The CPI for Information technology, hardware and services was 88.638 in the year 1991 and 7.328 in 2021:

7.328 / 88.638 * $20 = $1.65

Therefore, according to U.S. Bureau of Labor Statistics, $20 in 1991 has the same "purchasing power" as $1.65 in 2021 (in the CPI category of Information technology, hardware and services).
