Called the VA dpt of taxation and explained my situation
They said I only need to send my 760PY (2 pages), 760PY schedule of income (2 pgs), W2 form -- VA copy, and my tax return for my previous state.
I asked explicitly if I had to send the federal tax return or even the W2 copy for the federal tax return and I was told that no, it's not needed. She clarified that I could be contacted to provide more information if necessary, including my federal tax return, and that only in that case I should send it.
