jf:
You are posting in an already-answered thread from 2 years ago that has long been moved to a different queue. It will not show to the bulk of the forum as needing current help.
I can't help you with the gambling part, but I can comment on what you said about the OK return "taxes me on my own non-resident 9-5 income."
At this time of year, a lot of state products are still being finalized. It's possible the Form 511NR and associated forms that report on Form 511NR are not completely available yet. See this FAQ:

Your non-resident income, i.e., all income that is not Oklahoma-sourced should be excludable on a separate OK schedule where that is allocated and then reported back on the 511NR. I think I just found some info about it; see the next paragraph.
I'm not familiar specifically with OK state tax or their reporting forms, but I just looked briefly and with a quick search and glance at the instructions it looks like OK uses an extra page called 511NR-1 "Income Allocation for Nonresidents and Part-Year Residents." I looked at that Form 511NR-1, and it has 2 columns--one for Federal amount of each income type, and one for Oklahoma amount of each income type. TurboTax should fill that out for you in the OK state interview, and then in the final reporting it should exclude your non-resident income and use only the Oklahoma-sourced income.
I have seen how other states do it, so it may work the same way for Oklahoma. If you are a non-resident, I presume most of those income types in the Oklahoma column will have zeros if it's done the same way as other states. If your gambling winnings are your only "Oklahoma-sourced" income, then that may be your only entry in that OK column. Maybe you have not gone through the interview completely and haven't answered each screen to allocate the income, or it may be that that 511NR-1 allocation form is not yet available. Many states have forms that are not yet finalized and available. Did the interview offer a screen where you can allocate each type of income?
I'm a fellow user, not a tax person. If you need someone who is specifically knowledgeable about OK non-resident returns and how to allocate your non-Oklahoma and Oklahoma income, I may be able to find one to assist you. Or if you need help with reporting gambling winnings.
