Help - CSS Profile's additional requirements acronyms?

After submitting the CSS Profile I got a table of “additional requirements.” For some of the colleges there were letters indicating what the additional requirements were. I took a screenshot of the table with the letter codes but I did not capture what the letters themselves stood for. I thought they’d be on the CSS Profile’s website somewhere but I cannot find them. By any chance does anyone here know what they stand for? The letters A, G, H, I, J, and M. Thank you!

I logged in and chose

Under my list of school/requirement letters it says

Additional Requirements

If you have additional requirement codes above, read these special messages (below) from your colleges and programs. Provide any additional information requested directly to them, not the College Board. Contact the college or program if you have any questions about a message.

Ours only required B and H so those are the only ones I can see.

B = If the student has not already done so, he or she must submit the college’s or program’s application for financial aid, and supporting materials if applicable, directly to the college or program.
H = This college or program participates in the College Board’s Institutional Documentation Service (IDOC). In early February the student will be notified of where and how to submit his or her 2014 tax forms and other documentation. Please do not mail 2014 tax forms directly to this college or program.

A: Parents 2014 federal tax returns as soon as possible. Be sure to include student name and social security #.

G: Students 2014 federal tax returns.

I: Parents W2 forms, include student name and ss#

J: Student W2 forms

M: If parents own a business, submit the 2014 corporate return/partnership return/or statement of partner’s share of income; include student name and ss#

Good luck.
