I’m trying to program a song using note frequencies and when I look up the notes they are all major (like C which has a frequency of 261), but then in the music sheet there are major and minor notes and I don’t know the difference in Hz. I should also say I don’t know anything about music and I don’t really grasp the concept of chord and note and the difference between them.

Notes are not major or minor. It’s only the relationship between notes that is major or minor.
C and E is a major third interval, C and Eb is a minor third. On a well-tempered scale, the ratio of frequencies in a major third interval is 2^(4/12), about 1.26. In a minor interval it is 2^(3/12), about 1.19.
