While TurboTax does not support this form, you could enter the winnings under "Other Income". I would advise you to mail the return and attach Form 1042-S sot the IRS can match up the figures.
To enter the withholding:
You'll find the link to Withholding not already entered on a W-2 or 1099 under Federal Taxes > Deductions & Credits > Estimates and Other Taxes Paid. (Click the first screenshot below to enlarge it for reference.)

Hi, I'm in new territory here: In August I won money in OK and was given a 1042s form. For the past 6 yrs I've been filing form 1040 with Turbotax; now with this 1042s form I'm reading that I have to file form 1040nr!
Please advise.
Okay, there's a lot of information I don't know. Is this referring to Federal or State. If you are a US citizen you will not have to file a 1040 NR. If you are not a citizen you should have been filing one all along.
Now I expect that this will end up being about the states. If you do not live in OK and you won money in that state you will have to file a non resident return in OK. If you happen to live in TX there is no state tax so that will be the end of it. If you live in a different state that does have an income tax you will have to report your winnings there too. But, you will get a credit for the tax you paid in OK.
Thank you for replying. It's a federal return. Are you stating in need to file an OK tax return as well?
