I am in same situation as you. here is what I did and worked for me.
I submitted my W2 forms to Chicago with I485 application. Also I send a copy of employment confirmation which was reflecting all type of contracts that I was in with the university (like RA, TA,..)
For my interview I had the original ones + copy of all my previous and current contracts with university.
during the interview I saw that officer looked at the letter and copy of W2 forms and he did not say or ask for anything else. What I think is basically if you have enough income it does not make sense to ask for other supports even though one strange and not professional officer may ask for it.
For me, I did not have any option of preparing another form of support, if I could I would. so If you can prepare them, but if you can't I doubt that be a problem.

I will have my interview next week. I am currently on an F1 visa and I am being paid by the university. Does anyone know whether a letter from my university will be enough to prove that I will have enough money and I won't become a public charge in the US or I also need to fill out and sign an I864 form for myself? My income is above poverty line.
