You will have to check with Onin Staffing about that W2. They should have mailed the W2 out to whatever address of yours they had on record as of January 31st.
Some W2s have different information than others and not all of the employers on them are in the TurboTax database so the procedure for entering each W2 may differ. As long as all of the information is entered onto your tax return correctly that is all that matters.
