I'm from Argentina trying to fill a Utah tax refound. I'm not a resident from the USA but I worked there last winter season. Is there a special non-resident form?

The nonresident tax return is IRS Form 1040-NR.  TurboTax does not support a nonresident tax return.

 

See this TurboTax support FAQ for a Form 1040-NR - https://ttlc.intuit.com/turbotax-support/en-us/help-article/tax-forms/turbotax-handle-form-1040-nr-nonresident-aliens/L6XqFCkC3_US_en_US?uid=m7jgczti

NON RESIDENT ALIEN  

If you are a non-resident alien, your return must be filed on Form 1040NR, which cannot be prepared using TurboTax.  You can use TT’s partner, sprintax:
